Schneider Electric 8501XDO80 Industrial Control Relay

Schneider Electric's Square D 8501XDO80 is a NEMA Type X industrial control relay with eight normally open contacts driven by a 24 VDC coil. As part of the 8501XDO family, it provides electromechanical switching for multiple control circuits in a single compact housing, commonly used in machine-tool applications and general control panels. The eight NO contacts support parallel or sequential switching of auxiliary circuits, enabling straightforward wiring for logic signals and interlocks in industrial environments. The 24 VDC coil aligns with standard low-voltage control logic used by PLCs and automation modules, allowing reliable actuation from typical PLC outputs and sensor networks. This relay is designed for robust operation in industrial control schemes, delivering dependable control where low-voltage signaling must govern higher-energy loads. The 8501XDO80 family from Square D/Schneider Electric is a familiar choice for designers seeking a Type X NEMA relay with multiple contacts to consolidate control functionality, reduce panel space, and simplify maintenance in machine tools and automation equipment.
