WebThe 4-20 mA current loop is the dominant standard in many industries. It is the simplest option to connect and configure. It uses less wiring and connections than other signals, greatly reducing initial setup costs. Better for traveling long distances, as current does not degrade over long connections like voltage. WebThe thermocouple output is filtered externally and connects to a set of differential inputs, AIN1 (+) and AIN1 (–). The signal is then routed through a multiplexer, a buffer, and an instrumentation amplifier—which amplifies the small thermocouple signal—and to an ADC, which converts the signal to digital. ready field solutions llc
