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
