Two-Wired Signal Transmitter

Two-Wired Signal Transmitter is generally head mounted and fitted in the head of temperature sensor; Isolators provide further isolation of field signal so that the PLC side is isolated from the field side. Signal converters, isolators and transmitters isolate and convert field signals like Resistance, Current, Voltage, and Frequency to 4-20 mA. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping and non compatibility to standard processing unit.
Different models are available:

• SC IIID: Signal converter, DIN rail mounting, 4-20 mA I/P, 4-20 mA O/P
• ST N2PI: Temperature transmitter, head mounting, RTD I/P, 4-20 mA O/P, loop powered.
