Interface Relays

The 39 Series interface relays from Finder are ultra slim and only measure 6.2 mm,  are available in 5 different versions and suitable for interfacing with PLC-controlled automated systems. The model Plus allows for an extra protection on the output thanks to its replaceable fuse, which protects the relay output against overcurrent or short circuit. The models Input Master and Output Master allow a direct connection to the interface without the need for additional clamps. Input Master can be used in interface applications between the auxiliary contacts, sensors, limit switches and PLC’s. Output Master is suitable for interfacing between the PLC and relays, motors and solenoids.
