Relays and Optocouplers

From relay sockets to pluggable relay and optocoupler modules – WAGO delivers versatile, high-performance solutions for every application. They're perfectly suited for industrial automation, process and power engineering, rail systems, shipbuilding, and control cabinet manufacturing.

Product Overview

Our Relay and Optocoupler Products

Pluggable Control Relays

Our sockets with miniature switching relays combine compact housing with reliable electronics – ideal for switching tasks in industrial and process automation. Our relays offer up to four changeover contacts – perfect for dry circuits, lamp loads, and everything in between. Designed for easy maintenance, they enable quick relay replacement without disconnecting wiring.

Key Benefits:

  • Extensive bridging options on both control and contact sides
  • Quick and easy relay replacement in case of failure
  • Push-in CAGE CLAMP® technology for direct conductor insertion without tools
  • Visual status indication on the relay
  • Ex approval (Zone 2)
  • Push-buttons for intuitively opening connection points

Integrated Control Relay

The fully wired mounting carriers allow direct switching of actuators and other coupling elements in the field. They also enable quick and easy connection of peripheral signals. A comprehensive portfolio of relays with force-guided contacts is available for safety applications.

The Benefits for You:

  • Slim housing up to 6 mm saves space
  • Flat design for optimal use in terminal boxes
  • LED for status signal indication
  • Proven CAGE CLAMP® connection technology

Control Relay on a Rail-Mount Terminal Block

The relay modules plug directly onto the carrier terminal blocks of the WAGO TOPJOB® S and Classic Rail-Mount Terminal Block Systems for easy, secure installation. The combination of rail-mount terminal blocks and relay modules eliminates the need for an additional wiring interface.

The Benefits for You

  • Extended input voltage range for use in battery systems
  • Use in an extended temperature range (OT 4)
  • Ideal for railway applications
  • High vibration and shock resistance
  • Relay modules are more robust than elementary relays for replacement

Control Relay in a DIN-Rail-Mount Enclosure

Applications range from simple lighting control in building installations to installation in industrial control cabinets. Just 17.5 mm (0.689 inch) wide, the compact DIN-rail-mount enclosure is ideal for distribution cabinets and meter boards.

The Benefits for You

  • Extensive contact variants
  • Available with manual override
  • Each level can be commoned using push-in jumpers
  • Clearly identified connection points
  • LED for status indication

Pluggable Solid-State Relay

Our sockets with solid-state relays offer the perfect combination of a housing solution and electronics. These solid-state relays are ideal for switching applications in industrial and process automation. They offer noise-free, wear-free operation, e.g., for rapid decoupling of encoders and sensors.

The Benefits for You:

  • Long service life, especially for DC loads
  • Allows higher switching frequencies into the kHz range
  • Same design as WAGO Control Relays
  • Ex approval (Zone 2)

Integrated Optocoupler

We have a specialized portfolio of fixed-mount optocouplers for railway applications and shipbuilding. Thanks the wide variety of different versions, they are ideal for niche applications.

The Benefits for You:

  • Many different uses in AC and DC applications
  • Slim 6 mm (0.236 inch) housing saves space
  • Flat design for optimal use in terminal boxes
  • Jumper slots on the front for clearly organized cross-connections
  • LED status indicator

Solid-State Relay on a Rail-Mount Terminal Block

This category of solid-state relays offers easy, flexible pluggable connection to WAGO’s TOPJOB® S and Classic Rail-Mount Terminal Block Systems. Like the fixed-mount solid-state relays, they are ideal for railway and marine use or solutions for niche applications.

The Benefits for You:

  • Flexible use in AC and DC applications
  • Comprehensive commoning options
  • Durability
  • LED status indicator
