            • VARIMETER RCM - Reliably detect residual currents

              Unplanned interruptions of the operation of machines and systems are a significant cost factor. Insulation errors are a frequent cause for this. In grounded networks (TN networks), DOLD difference current sensors ensure reliable residual current monitoring. Expensive standstill time is avoided by this and, in addition, a possible risk of fire that latently exists by a gradual insulation error is also prevented. The difference current sensors are universally deployable as they can detect both direct and alternating current.
            • Insulation monitors

            • VARIMETER IMD - Convincing solutions for insulation monitoring

              Unplanned standstills of machines and systems as a result of insulation errors can have serious consequences. By detecting such errors in ungrounded networks (IT networks) early on, DOLD insulation monitors prevent outages of electrical systems and thus guarantee higher operating and system security. The system operator is informed early on about pending critical operating conditions and people and machinery are protected by the insulation monitoring. The functionality of DOLD insulation monitoring devices has been intentionally designed simply. You profit twice over from this: through high user-friendliness as well as cost savings.
            • Equipment for insulation fault location

            • VARIMETER EDS - Precise error localisation during ongoing operation

              In complex industrial systems, the localisation of insulation errors can be expensive and time-consuming. The insulation error search system from DOLD allows an automatic and fast localisation of faulty electrical circuits in complexly insulated AC/DC networks (IT systems) and this increases reliability and system availability. Thanks to the low maintenance costs and the avoidance of interruptions in operation, the investment costs for the DOLD insulation error search system are amortised quickly.

We can provide you with both mono-functional and multifunctional relays with which you can realise your solutions with minimal costs or maximum flexibility and functionality.

            • Fault annunciators

            • Interference suppressor systems for systems and buildings

              DOLD interference suppressors of the INFOMASTER family use lamps, signals or text notifications to inform about interferences and the conditions of electrical systems in industrial settings and buildings. In addition, they are also used to define maintenance intervals for preventive maintenance. Especially in the event of interferences in complex machine and systems, they can decisively reduce the length of the search for interferences. This minimises standstill times of the production system and helps to save on costs. The compact DOLD interference suppressor ensures a cost-efficient monitoring of small machines without SPS, such as compressors. Thanks to it modular construction, it can grow with the system through expansions.

              • Timers

              • Safe relays for applications with high demands

                DOLD has been a renowned, innovative manufacturer in the field of timer technology for decades that has continued to set standards with its developments. Time relays, that is, relays with specific time response, help you to cost-effectively realised start-up and shut-down delays in industry and building technology. The timer technology from DOLD includes both electro-mechanical and electro-pneumatic time relays as well as electronic devices on the basis of modern microprocessor technology.
                  • Multifunction relays

                  • Universally usable - maximum function in minimum width

                    Multifunctional relays are universally usable thanks to the selection of the corresponding function. They also belong to the group of time relays with which you can cost-effectively realised specific time functions. A multifunctional relay can be used as a flasher relay, clock, impulse former, start-up and/or shut-down relay as well as contact and recurrence delay. You can simply set the respective function on the device.
                  • Flasher

                  • Control of malfunction notifications and position lights

                    DOLD flasher relays are used on cranes, wind power systems as well as airfield lighting where they control position lighting. The control of malfunction notifications on machines, lighting, fans, et cetera is an additional task of these devices. Impulse time and pause time are identical with flasher relays.
                  • Cycling timers

                  • Impulse and pause times configurable independent from each other

                    Clocks from DOLD are important components of traffic light control systems, automatic ovens, et cetera. They have the same function as flasher relays with the difference that the impulse and pause times for time-dependent control systems are different from each other and can thus be set separately.
                  • Fleeting action relays

                  • Input and output wiping relays for time-dependent control systems

                    Machines and systems such as dosing systems and rinsing systems are where wiping relays are used. DOLD wiping relays are available as both input as well as output wiping relays. While the input wiping relays immediately switch the operating voltage to the work position after installation, output wiping relays are placed over the voltage control contact on the control input. If this is open, the relay immediately switches to the work position. Both relay types switch back to resting position immediately after the expiration of the set wiping time.
                  • Timers on delayed

                  • Time relays with contact delay for forward switching

                    With contact delayed time relays, the start is triggered by the activation of the operating voltage. The relay switches to the work position after the expiration of the configured delay time. Contact delayed time relays from DOLD are used for forward switching, e.g. pre-heating, or for delay times in switching systems such as for the delayed activation of system parts in burner controls, escalators and elevators.
                  • Timers off delayed

                  • Time relays with recurrence delay for forward switching

                    For time relays with recurrence delay, we distinguish between devices with and without auxiliary voltage. While devices without auxiliary voltage are only realisable for short times, those with auxiliary voltage are also suitable for longer periods of time. Repress delayed time relays from DOLD are used for follow-on switching (e.g. fans), lighting control systems (e.g. stairwell lighting) or for the delayed switching to an emergency power generator and/or an emergency lighting system.
                • Installation electronics

                • Innovative installation devices so that you aren't left standing in the dark

                  DOLD offers you a wide palette of products for installation technology. These basic devices for modern building automation ensure that you aren't left standing in the dark or ensure that energy is reasonably saved over the scope of the lighting controls. Alongside timers and remote switches, energy-saving switches and load shedding relays, additional installation devices, such as Venetian blinds switches, network relays or the innovative hybrid switch relays round out the coordinated DOLD programme of installation devices.

                    • Time switches

                    • Timer for saving energy and costs

                      With DOLD timers, you can save energy and costs by avoiding unnecessarily long activation times for lighting and other electricity consumers. The usage spectrum for timers is vast and ranges from stairwell and hallway lighting to courtyard lighting to follow-on controls for bathroom ventilation fans. Additional cost benefits from space savings result from the compact construction of the device. The continuous lighting function ensure that lighting is not interrupted during longer activities.
                    • Remote control switches

                    • Switch lighting on and off from any number of locations

                      In large office buildings, factories, hospitals, schools, public buildings, et cetera, one often has to individual turn different lamp groups on or off. At the same time, it should be possible to turn all lamps on in the morning or off at night with a central control command, possibly only by authorised personnel. You can realise central and group switching very easily with remote switches from DOLD. You can connect any number of unlit push buttons to a remote switch. The distances between the push buttons and the remote switch barely plays a role.
                    • Specific installation devices

                    • Special installation devices for building technology

                      This product group from DOLD includes the energy-saving switch, the hybrid switch relay and the network relay. You can save energy and costs with the energy-saving switch which is a combination of a timer and remote switch. With it, you can turn off the lighting in a controlled manner before the expiration of the time configured. Alongside lighting, it also makes sense for fans, dryers and other electricity consumers that seldom have to be immediately turned back on after being used. The hybrid switch relay is used in heating, ventilation, air conditioning and lighting technology for the switching of strongly inductive and/or capacitive loads such as energy-saving lamps. Electro-smog can be avoided with DOLD net relays. They are used to deactivate the power supply of electrical circuits in bedroom or other rooms sensitive to electro-smog.

                      • Safety relays with forcibly guided contacts

                      • Energy efficiency and safety for your applications

                        In the machine- and plantbuilding sector the safety becomes more and more important. Everywhere, safety modules and also safety control systems are used. Despite the increasing use of semiconductor relays, the electromechanical relays are still an important part. Safety relays, i.e. relays with mechanically forcibly guided contacts per DIN EN 61810-3, are used wherever people, machines and valuable goods must be protected from injury and damage. One such relay comprises at least one NC contact set and one NO contact set and is constructed such that the NC set and the NO set can never be closed at the same time. For example, if a NO contact fails when trying to open, the associated NC contact cannot close when the power supply is switched off.
                      • PCB relays

                      • PCB relays, also known as plug-in/print relays, are used for galvanic separation of circuits as well as for signal adaptation and signal strengthening. Our vertical and horizontal designs enable optimum adaptation to your application. DOLD PCB relays, with max. continuous currents up to 16 A, are available with one or two contacts, in different installation heights and with different contact materials.
                      • Miniature relays

                      • Highest switching safety on smallest space

                        If it is necessary to switch heavy currents reliably in a small space and galvanic separation of control and load circuits is also required, there is no better answer than the compact miniature power relays available in SMD (Surface Mount Device) form and in DIL (Dual In-Line) form.

                            A part of Dold’s extensive enclosure range, is provided in two complete Series of distribution enclosures. Series KU 4000 requires a mounting depth of only 55 mm, with Series KU 4100 providing even more space for your electronics. Both the KU 4000 and KU 4100 Series offer enclosure widths from 17.5 mm to 140 mm, having up to 64 and 96 terminals respectively. In addition to various terminal options, there are several BUS-connections available.

                            This enclosure series fulfils all the requirements for the modern building automation system. With its variant diversity, also individual task assignments can be solved without problems. Also the enclosure size can be adapted gradually to the application. So the enclosure series covers all common mounting widths from 8.8 to 140 mm. For connecting the devices, along with the conventional, undetachable screw-type terminals, also cage tension-spring clamps for particularly economical installation of the devices are available. Also stronger currents can flow and high-voltage current pins of up to 50 A can be used. It goes without saying that for connecting and communication with other devices and systems also various connections can be realised such as, for example, BUS connections, KNX (EIB), RJ-45, etc. The enclosures are designed both for top-hat rail and screw attachment.

With its high flexibility, this concept allows a variety of custom solutions. The In-Rail Bus replaces the costly individual wiring by an uninterruptible and flexible system solution. It is safely integrated in a standard 35 mm top-hat rail. Perfectly fitting carrier sections allow the use of standard rails with a height of 7.5 mm or 15 mm.
                                • Safety switch, Guard lock, Key transfer

                                • Safety switch, solenoid guard lock, trapped key interlock and command function in one system

                                  Safety with System. The special thing about SAFEMASTER STS is the system concept and the simple design which allows any conceivable variant, from the smallest standard solution to a complex safety system. Any solution remains flexible, unique and economical thanks to the modular design principle.
                                    • Safety switch

                                    • Electromechanical safety switches monitor accesses and safety gates

                                      SAFEMASTER STS series safety switches reliably secure access and protective doors and hatches, and are suitable for safety applications up to Cat. 4 / PL e in accordance with EN ISO 13849-1 without fault exclusion. They are suited for applications requiring a high level of security. The very narrow design also allows them to be installed on movable safety guards.
                                    • Guard lock

                                    • Electromechanical solenoid locking units prevent the opening of access or safety gates

                                      Guard locks in the SAFEMASTER STS family combine our trusted mechanical principle with the advantages of electromechanical safety switches with a 2-channel locking function. Thanks to their lock monitoring features, they can be used to reliably protect both processes and personnel. Different coding levels, very high locking forces, and comprehensive diagnostic capabilities allow them to be used in almost all safety-relevant applications.
                                    • Key transfer

                                    • The key transfer system combines the advantages of none wiring, mechanical safety with electrical safety

                                      The basic principle of the key transfer system ensures that a machine or system is in a safe state before an access can be made. A further safety aspect is that a key is inserted either in a safety switch or can be used for opening a door lock. This property can be used to force a certain operating sequence, which can not be deviated from. As a result, a high safety level is achieved and a large number of different danger areas can be ensured.

                                    • SAFEMASTER STS - Individual moduls

                                    • Flexibly, individually and perfectly adapted to your applications

                                      The modularity of the SAFEMASTER STS allows individual adaptions to the corresponding applications. By means of bayonet locks (see accessory) any number of units can be mounted of only a few basic modules. The function of the units are defined from the way and arrangement of the modules, whereby several unities form a system. The possible combinations of the composed unities determine the individual functions of the total system.

                                    • Command devices

                                    • The robust stainless steel option module expands the modular SAFEMASTER STS safety switch and key transfer system with variable command, indication, selection and emergency stop functions. This turns the system into a true "control centre" from where command functions, status displays, release signals, main and maintenance access points can be controlled. The option module is form-fitting and can be installed directly underneath safety switches or hold closed units thus enabling direct command execution at the access points for machines and systems. It can also be installed as a standalone command device. You too can benefit from the high degree of system flexibility.
