With 4 CO (4PDT) contacts rated 7 A and a 230 V AC (50/60 Hz) coil, the Finder 55.34.8.230.0040 is one of the most widely used interface relays in control panels. A plug-in relay can be replaced in seconds without rewiring: pull the old relay from its socket and push in the new one with the same code.
Relays like this one separate PLC outputs and control circuits from the loads they switch: contactor coils, solenoid valves, lamps and small motors. Finder gives a single-phase motor rating of 0.24 kW at 230 V AC.
