Frequency Relays, N96D-FR

The N96-Digital Frequency relay monitors the Frequency of the circuit continuously . The N96DFR shall have 2 set points , one for Under Frequency (UF) & other for over Frequency (OF). When Frequency goes out of the range selected , the respective relay status will change .The relay checks for its healthiness first & then starts monitoring voltage signal. The relays are provided with common settable trip time delays .Digital FR has a facility for user to program AUTO/MANUAL RESET and NORMAL/FAIL SAFE TRIPPING of relays. Also it has connectivity of RS232/485 as an additional option. User can program the relay for Under , or Over Frequency or both combined protections.
