DFB01CM24

DFB01CM24 is a precise frequency monitoring relay. This relay monitors their own power supply from 24 to 240VAC. 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 LEDs indicate the state of the alarm and the output relay.
