Abstract
A device includes a device input, an output connector configured to connect to a current loop, and current loop transmitter circuitry. The current loop transmitter circuitry receives, via the device input, an input from a dry contact switch, and translates a state of the dry contact switch to a current loop current. The current loop transmitter circuitry transmits the current loop current via the output connector through the current loop.
