Wago 750-516 4Do, 24 Vdc 0.5A Lss

Why Choose the WAGO 750-516 Relay Output Module?

The WAGO 750-516 is a versatile 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, signal lamps, valves and motors in distributed automation systems.

Each channel provides a potential-free changeover relay contact (SPDT) capable of switching loads up to 250 V AC or 30 V DC. The relay contacts support switching currents up to 2 A per channel, allowing safe and reliable control of higher-voltage loads while maintaining electrical isolation between 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 compact DIN rail design and CAGE CLAMP® spring terminal technology allow fast installation and secure wiring within industrial control cabinets.

Industrial Relay Output Control

Relay output modules are widely used in automation systems to control devices that require higher switching voltages or currents than semiconductor outputs can provide. Changeover relay contacts offer flexible switching options, allowing devices to be controlled in either normally open or normally closed configurations.

The WAGO 750-516 allows automation systems to reliably control equipment such as contactors, pumps, motors and signalling devices. When integrated into the WAGO 750 distributed I/O platform, it provides scalable and reliable output control for industrial automation and machine control systems.

Typical Applications

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