RPL23 monitoring relay allow to detect overvoltage, under voltage, over frequency, under frequency, asymmetry, phase
failure and phase order of a three-phase or a single phase low voltage or high voltage network.
Characteristics:
- Line voltage monitoring with or without neutral of three phase network, single phase network or continuous (DC)
voltage.
- Versatile auxiliary power supply.
- 2 alarm relays in case of overvoltage, under voltage, phase asymmetry and over/under frequency.
- 1 phase order monitoring relay (option /Po).
- Response time of alarm relay adjustable up to 600 seconds.
- Alarm memorization (HOLD function).
- Fault indication by falling output relay.
- Power supply voltage LED.
- Faults LEDs : phases sequence error, under/over voltage, under/over frequency, phase failure.
- Alphanumeric 4 digits display for measures visualization and device configuration.
- 2 push buttons for device configuration and for acknowledge a memorized failure.
