Line Voltage Monitoring
ICM492DX
Single-Phase Line Voltage Monitor
The ICM492DX continuously monitors incoming line voltage for faults and displays RMS voltage on the digital display. When the line voltage is appropriate, the ICM492DX will close the COM and N.O. relay contacts. When the incoming line voltage is outside of the user selected parameters, the ICM492DX will close the COM and N.C. relay contacts and indicate a fault condition by flashing the fault LED.- Protects against over and under voltage, and rapid short cycling caused by transient faults and power interruptions
