Wago 750-514 2Do, 125 Vac 0.5A Pot-Free Relay2No

Why Choose the WAGO 750-514 Relay Output Module?

The WAGO 750-514 is a dependable 4-channel relay output module designed for the WAGO I/O System 750. It enables PLCs and industrial controllers to switch field devices such as contactors, signalling lamps, motors and relay coils in distributed automation systems.

Each channel provides a potential-free electromechanical relay contact capable of switching loads up to 250 V AC or 30 V DC with a maximum switching current of 2 A. The relay contacts provide reliable electrical isolation between the control electronics and field circuits, allowing safe switching of higher-voltage loads.

The module integrates seamlessly with WAGO fieldbus couplers and programmable controllers as part of the modular WAGO 750 distributed I/O architecture. Its compact DIN rail housing and CAGE CLAMP® spring terminal technology allow quick installation and secure wiring in industrial control cabinets.
