WAGO Solid-State Relay Module 24 VDC Input, 0-24 VDC Output, 3 A (857-724)

WAGO 857-724 is a 6 mm wide DIN-rail solid-state relay module with a nominal 24 VDC input and an output range of 0 to 24 VDC at up to 3 A continuous. The two-wire load connection uses Push-in CAGE CLAMP terminals for 0.34 to 2.5 mm² conductors, and a yellow LED indicates output status. Suitable for switching DC loads from PLC signals in industrial control cabinets; reinforced insulation between adjacent modules of the same type.
