Abstract
A circuit interrupter includes a sensor structured to output a sensor signal, a control unit structured to receive an external control signal, the control unit including: a communication interface structured to receive the external control signal, and a waveform generator structured to generate a waveform equivalent to the sensor signal in response to the external control, and a signal processing circuit structured to receive and process the sensor signal or the generated waveform and to output the processed sensor signal or generated waveform to the control unit.
Claims15
A circuit interrupter comprising:
- a sensor structured to output a sensor signal;
- a control unit structured to receive an external control signal, the control unit including:
- a communication interface structured to receive the external control signal, and
- a waveform generator structured to generate a waveform equivalent to the sensor signal in response to the external control signal;
- and
- a signal processing circuit structured to receive and process the sensor signal or the generated waveform and to output the processed sensor signal or generated waveform to the control unit.
A system comprising:
- an input device including a waveform generator structured to generate a waveform;
- and
- a circuit interrupter comprising:
- a sensor structured to output a sensor signal;
- a control unit structured to receive the generated waveform and to output the generated waveform;
- and
- a signal processing circuit structured to receive and process the sensor signal or the generated waveform and to output the processed sensor signal or generated waveform to the control unit,
- wherein the waveform generator is structured to generate the waveform equivalent to the sensor signal,
