Open/Close Coil Current



The Open/Close Coil Current sensors are used in place of or in addition to the CCA to monitor switch actuation.

  • ASSIST enabled
  • Uses a signal port
  • Monitors open/close switch actuation
  • Easy to install

Switch actuation is determined by monitoring the current in the control circuit. The sensor provided is a single channel dual probe (i.e., one probe for open and one probe for closed in a single sensor). Depending on the control circuit being monitored and the placement of the probes, more than two switches can be monitored (e.g., the bypass and the torque switch on an MOV can both be monitored with the close probe).
