DFB01 and PFB01 are precise frequency monitoring relays. The relays monitor their own power supply from24 to 240 VAC.The advantage of using the latch function is that the relay can be kept energized even after the end of the alarm condition. Inhibit function can be used to avoid relay operation when not desired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.
