Monitoring Relays Frequency Monitoring Types DFB01, PFB01
DFB01 PFB01
• Over/under frequency monitoring relays
• Measuring if power supply frequency is within set limits
• Measure on own power supply
• Measuring ranges Voltage: 24 to 240 VAC Frequency: 50 - 60 Hz
• Separately adjustable upper/lower level on relative scale
• Adjustable delay on alarm or on recovery (0.1 to 30 s)
• Programmable latching or inhibit at set level
• Output: 8 A SPDT relay N.D. or N.E. selectable
• For mounting on DIN-rail in accordance with DIN/EN
50 022 (DFB01) or plug-in module (PFB01)
• 22.5 mm Euronorm housing (DFB01) or 36 mm plug-in module (PFB01)
• LED indication for relay, alarm and power supply ON
Product Description Ordering key DFB 01 C M24
DFB01 and PFB01 are pre- cise 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.
