The CNCS provides power sensing of any single AC powered device or AC load up to 5 Amps. A current sensor is typically used with any television, AV receiver, etc. to provide confirmation of the device's power on/off state. This is often necessary to enable reliable power control for IR controlled devices that do not include discrete power commands in their IR control protocol.

The CNCS provides true power status feedback to the control system via a pair of low-voltage contact closures, which may be connected directly to Versiports or other digital input ports on any Crestron control system, room box, expansion module, etc. Although the CNCS is not a Cresnet device, it does require power (24 and G) from the Cresnet bus.
