Signal Converters, Isolators & Transmitters

Protocontrol offers Signal Converters, Isolators and Transmitters, which are to isolate and convert field signals like resistance, current, voltage, and frequency to 4-20 mA. These isolators find use in process control industries for signal isolation. Variety of models is available for specific applications. Signal converter converts field signals received from sensors like RTD, thermocouple, load cells, strain gauge to standard 4-20 mA form which is acceptable at PLC or DCS for further processing. Transmitters are generally head mounted and fitted in the head of temperature sensor; Isolators provide further isolation of field signal so that PLC side is isolated from field side.
