Details for CTD-C2G00-1



The Current Transducer Device (CTD) Series of analog output current transducers are nonintrusive devices designed to monitor current flowing through a cable or wire. These units are a cost-effective solution for monitoring load or proof of operation. The current transducers are ideal for monitoring current loads on pumps, driving fans, and blowers, and sensing the status of heating coils and lighting. CTD devices used for load trending over time are effective sensors for predictive maintenance programs.

These units are available with standard 4 to 20 mA current loop, 0 to 5 VDC, and 0 to 10 VDC analog output. The voltage output models derive excitation by magnetic induction from the current-carrying conductor (wire or cable), making these units completely self-powered. The current loop output model requires a 24 VDC power supply.

Optional command relays (CR-01200-0 and CR-02400-0) provide externally controlled auxiliary contacts when used with the current transducers. The relays offer a cost-effective solution for switching loads that require higher power levels than the rating of the current switch contacts, or the need to mount an external relay elsewhere in the control enclosure.


  • clamped/split core design — reduces installation time and associated costs
  • slide switch, selectable amperage ranges — provides a wide array of amperage ranges to match the application
  • multiple outputs: 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC — provide the appropriate output for the specific application
  • snap-on power relay — provides an easy way to add an external relay to the current sensor • relay (optional) LED indication Off/On status — allows you to easily check the relay’s on/off status
