Monitoring Relays Frequency Monitoring Types DFB01 PFB01

Update: 30 September, 2023

DFB01 and PFB01 are precise frequency monitoring relays. The relays monitor their own power supply from 24 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 func- tion can be used to avoid relay operation when not desired (maintenance, tran- sitions). The LED's indicate the state of the alarm and the output relay.
