Product Overview
Our Relay and Optocoupler Module Products
Controlling Night-Time Marking of Wind Turbines
In the future, wind turbines will only be allowed to flash red when aircraft approaches. This should reduce light emissions. Deutsche Windtechnik Steuerung has developed a transponder-based system to control this on-demand night-time marking (German: BNK; English: ADLS), which includes WAGO technology.
Brief Current Peaks with Fatal Consequences
When lighting systems switch on, significant current spikes occur that can far exceed 100 times the nominal current. Even if this current is only present for a few milliseconds, it can cause the relay contacts to fuse.
Here you’ll learn how our relays work so you can enjoy your system for a long time.
Long Cable Lengths in Large Systems
In this video, you’ll see how sensor signals are transmitted in large systems with long cables through the example of a sewage treatment plant. In this application, WAGO relays with RC base load modules minimize unwanted voltages with low losses. In addition, they make defined switching behavior possible in order to keep large systems functioning perfectly.
The 788 Series Relays are ideal for switching applications in industry and process automation. These relay modules can be used either for two-channel operation or for safe switching of high loads up to 16 A (e.g., lamp loads).
Your Benefits:
The 859 Series Relay Modules with miniature switching relays and optocoupler modules are ideal for interface levels in all industrial applications. Their slim design saves you space in the control cabinet. Simple commoning on the control and load side also allows you to quickly daisy-chain common input and output potentials.
Your Benefits:
The 2042 Series Relay Modules plug directly onto the carrier terminal blocks from the WAGO TOPJOB® S Rail-Mount Terminal Block System for easy and secure installation. The combination of rail-mount terminal blocks and relay modules eliminates the need for an additional wiring interface.
Incredibly robust, these modules withstand high vibration and shock loads. For example, they meet the requirements of the DIN EN 61373 (vibration and shock) and DIN EN 50121-3-2 (EMC) railway standards.
Your Benefits:
The fully wired 287/288 Series Mounting Carriers with miniature switching relays allow direct switching of actuators and other coupling elements in the field. They also enable quick and easy connection of peripheral signals.
Your Benefits:
The 789 Series’ applications range from simple lighting control in building installations to installations in industrial control cabinets. The 17.5 mm (0.689 inch) wide design in a DIN-rail-mount enclosure is particularly well-suited to installation in distribution cabinets and meter boards.
Your Benefits:
The 857 Series Sockets with miniature switching relays and solid-state relays perfectly combine a housing with electronics.
Your Benefits:
The 858 Series Sockets are designed for DIN-35 rail mounting and thus for commercially available industrial relays with standard pin spacing. They can accommodate relays with two or four changeover contacts. In practice, the sockets allow rapid relay replacement for servicing without disconnecting the wiring.

Maximize Space in the Control Cabinet
New Solid-State Relay Module with Lower Power Loss at Higher Load Current
Making the best possible use of the limited space available is essential in control cabinet manufacturing. The new solid-state relay module (SSR module) can help: It switches a limiting continuous current up to 8 A. Due to its low power loss, it generates significantly less heat. This makes it possible to achieve high-density wiring – i.e., a larger number of switching elements – within a control cabinet with the same total power loss.
SSR modules are suitable for applications where a coupling level is required between the PLC and the load that is to be switched. Since they operate without moving parts, there is no mechanical wear. As a result, they offer a long service life, switch silently and are insensitive to shock and vibration. WAGO’s SSR modules use sockets that are pin-compatible with standard relays, making it very easy to replace a relay.
