Monitoring Relays
Frequency Monitoring
Types 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)
DFB01
PFB01
• LED indication for relay, alarm and power supply ON
