An isolation device, a control system, and a method are disclosed. An illustrative system is disclosed to include a first power domain in which a first emitter is disposed. The system further includes a third power domain in which a second emitter is disposed. The system also includes a second power domain in which a detector is disposed, where the second power domain is electrically isolated from both the first power domain and the third power domain, where the detector is configured to receive a first control signal from the first emitter as well as a second control signal from the second emitter and produce an output in response thereto that represents a combination of the first control signal and the second control signal.

Galvanically isolated auxiliary LED for performing input operations

An isolation system and isolation device are disclosed. An illustrative isolation device is disclosed to include first circuitry having at least a first emitter and a first detector, second circuitry having at least a dual-purpose component, an isolation material configured to electrically isolate the first circuitry from the second circuitry, and switching circuitry adapted to connect the dual-purpose component to emit a first signal for detection by the first detector in a first configuration, and to receive a second signal from the first emitter in a second configuration.
