Wago 750-515 4-channel digital output; AC 250 V; 2.0 A; Potential-free; Relay, 4 make contacts

Why Choose the WAGO 750-515 Relay Output Module?

The WAGO 750-515 is a compact 4-channel relay output module designed for the WAGO I/O System 750. It enables PLCs and automation controllers to switch higher-voltage field devices such as contactors, signalling lamps, solenoid valves and motors in distributed industrial control systems.

Each channel provides a potential-free electromechanical relay contact capable of switching loads up to 250 V AC or 30 V DC. The module supports switching currents up to 2 A per channel, allowing safe control of a wide range of industrial loads while maintaining electrical isolation between the control electronics and field circuits.

The module integrates seamlessly with WAGO fieldbus couplers and programmable controllers as part of the modular WAGO 750 distributed I/O architecture. Its slim DIN rail design and CAGE CLAMP® spring terminal technology provide fast installation and secure wiring inside industrial control cabinets.

Industrial Relay Output Control

Relay output modules are widely used in automation systems to control loads that require higher switching voltages or currents than semiconductor outputs can provide. Electromechanical relay contacts isolate the PLC electronics from field circuits, enabling safe switching of AC or DC loads.

The WAGO 750-515 allows industrial controllers to reliably switch devices such as contactors, pumps, signal lamps and actuators. When integrated into the WAGO 750 distributed I/O platform, it provides a flexible and scalable solution for machine automation and industrial process control systems.

Typical Applications

• Switching contactor and relay coils.
• Industrial signalling and indicator lamps.
• Machine automation and equipment control.
• Building automation and HVAC systems.
• Distributed PLC and remote I/O architectures.
