Wago 750-552 2Ao, 0-20Ma

Why Choose the WAGO 750-552 Relay Output Module?

The WAGO 750-552 is a compact 2-channel relay output module designed for use within the WAGO I/O System 750 and 753 distributed automation platform. It allows PLCs and fieldbus controllers to switch AC or DC loads using mechanical relay contacts, creating a flexible interface between low-voltage control signals and external electrical equipment.

Each output channel provides a potential-free relay contact capable of switching higher voltage loads compared with standard digital outputs. This makes the module suitable for controlling contactors, solenoid valves, motors, alarm systems and lighting circuits across industrial automation and building control applications.

With its slim 12 mm module width, the 750-552 enables high-density installations within control cabinets. The module features WAGO’s reliable CAGE CLAMP® spring pressure connection technology, allowing quick wiring, vibration-resistant connections and long-term maintenance-free operation.
