Product Overview

The IL 9077 series Voltage Monitoring Relay with asymmetry identification as an option. All 3-phase voltages are measured with N. If it is in the acceptable range, a green LED goes on and the output relay is activated. If at least one phase exceeds the setting value for overvoltage or if at least one phase falls short of the setting value for undervoltage, the output relay releases after the set time delay and the green LED goes off (fault state). 2 red LEDs then indicate the cause of the fault of undervoltage <U and an overvoltage >U. When all 3-phase voltages are below the chosen setting value for overvoltage and above the chosen setting value for undervoltage again, the relevant red LED goes out, the output relay is activated again and the green LED goes on again (acceptable state). When the system returns to an acceptable state, there is a hysteresis of about 4% of the set value with both the set voltage thresholds.
  • Identification of overvoltage, undervoltage and phase failure
  • Mains fault diagnostics with a number of LEDs
  • Setting values for overvoltage and undervoltage can be set separately
  • Closed circuit operation
  • No auxiliary voltage
  • Independent of phase sequence
  • As option with phase sequence detection
  • Single-phase connection possible
  • Optionally for 3P3W systems
  • 2 Changeover contacts, at 2 x 2 changeover contacts
  • Time delay variable between 0.1 to 20sec
  • According to IEC/EN 60 255, DIN VDE 0435-303
