Fuse monitors are CSA C1D2 certified
CSA Class 1 Division 2 certified, Emphatec’s DEPRO fuse monitors monitor up to 8 fuses or circuit breakers and provide a 1 form C (SPDT) relay contact to indicate a failure. The modules operate as a logic AND device. If all 8 inputs are energized the output relay is energized. If one or more inputs are lost the relay switches off. If the application calls for less than 8 inputs then the unused channels are bypassed using a DIP switch with no need to jumper the unused channels.
Two versions are available – one for 24 Vdc applications and one for 120 Vac applications. The modules are powered from the same voltage as they are monitoring meaning no auxiliary supplies are needed. All connections are via plug and socket connections for easy installation. The compact package requires 27 mm of DIN rail and can be mounted on 15, 32 or 35 mm rails.
