Finder 7S.14.9.024.4310 MasterINTERFACE Interface Relay, 24V DC Coil, 3NO+1NC, 6A, DIN Rail

In industrial control cabinets, the Finder 7S.14.9.024.4310 interface relay bridges low-power PLC outputs and higher-current loads. It switches up to 6 A at 250 V AC, making it suitable for contactors, solenoid valves, and small motors. The 24 V DC coil matches standard automation supply voltages, and the 3 NO + 1 NC contact arrangement offers flexible control logic.
