Relay and Optocoupler Modules
Whether relay sockets or pluggable relay and optocoupler modules, WAGO's array of relays and optocouplers offer a solution for any requirement. Use them in any sector of industry including process technology and power engineering, railway applications and machine engineering, as well as general control cabinet construction.
Our Relay and Optocoupler Module Products
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.
WAGO's 788 Series Relay Sockets are ideal for switching applications in both industrial and process automation. These modules can be used either with two channels or for reliably switching higher loads (e.g., lamp loads) up to 16 A.
WAGO's 859 Series Relay Modules with a Miniature Switching Relay and Optocoupler Modules are ideal for any industrial interface applications. Their slim design saves valuable control cabinet space. Simple commoning at the control and load side streamlines looping through of common input and output potentials.
WAGO's 2042 Series Pluggable Relay Modules plug directly onto the carrier terminal blocks from the WAGO TOPJOB® S Rail-Mount Terminal Block System for easy and secure installation. This combination of rail-mount terminal blocks and relay modules saves the user an extra wiring level.
Incredibly robust, the 2042 Series Modules withstand high vibration and shock loads, and meet both DIN EN 61373 (vibration and shock) and DIN EN 50121-3-2 (EMC) railway standard requirements.
WAGO's fully wired DIN-rail-mount carriers with a miniature switching relay (287/288 Series) provide direct, in-the-field switching of actuators and other coupling elements. They also permit fast and easy peripheral signal connections.
WAGO's 789 Series Relay Modules serve a wide variety of applications, from basic lighting control in building installations to industrial control cabinet installations. Just 17.5 mm (0.689 inch) wide, the compact DIN-rail-mount enclosure is ideal for distribution boards and meter cabinets.
WAGO's sockets with a miniature switching relay or a solid-state relay are the perfect combination of housing and electronics.
WAGO's DIN-35-rail-mount 858 Series Relay Sockets are designed for conventional industrial relays with standard pin spacing. These sockets carry relays equipped with two or four changeover contacts. During maintenance, they allow quick relay replacement without removing conductors.
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.
