Ground sensing relay
WebSep 20, 2012 · Current-sensing relays are used to: Signal high-current conditions, such as a clogged grinder. Identify low-current conditions, such as a pump that has encountered a low-water condition. Sense the current a motor is drawing to feed the current to a programmable logic controller (PLC). WebDG Series Ground Fault Relay keep machinery and their operators safe from accidental shocks. The one-piece, solid-core design allows for installation over wires feeding loads to about fifty amps. The output relay will change state at factory setpoint between 5 and 50 mA of DC current to earth. Check Distributor Stock.
