Diligent Micro Controls has also developed protection relays for DC loads such as DC motor, DC generator, Rectifier sets, DC electromagnet etc. These relays are available in three types: namely INS tantaneous, Time-Delayed and Jam type similar to the AC relays. DC relay operate from 75 mV standard DC shunt and require auxiliary supply for its operation. Optionally the relay can be made suitable to work with User-specified shunt.
