DFB01/PFB01 Frequency Monitoring Relay
Carlo Gavazzi DFB01 and PFB01 series precise frequency monitoring relays. The DFB and PFB relays monitor their own power supply from 24 to 240 V ac. The relays offer a latch function that can be kept energized even after the end of the alarm condition. An Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The front facing LED's indicate the state of the alarm and the output relay.
