Wago 750-550 2Ao, 0-10 Vdc

Why Choose the WAGO 750-550 Relay Output Module?

The WAGO 750-550 is a versatile 2-channel relay output module designed for integration with the WAGO I/O System 750 and 753 distributed automation platform. It enables PLCs and fieldbus controllers to switch electrical loads using mechanical relay contacts, making it suitable for controlling AC and DC devices across industrial automation systems.

Each channel features a potential-free relay contact capable of switching a wide range of loads, including higher voltage AC circuits and DC control devices. This flexibility allows the module to interface between low-voltage PLC signals and external equipment such as motors, solenoid valves, alarm systems and signalling devices.

With its compact 12 mm module width, the 750-550 allows efficient use of cabinet space while maintaining the reliability expected from the WAGO I/O platform. The module incorporates WAGO’s proven CAGE CLAMP® spring pressure connection technology, ensuring fast installation, vibration resistance and maintenance-free wiring in industrial environments.
