Transmitter

Dataforth’s new DSCT series of loop powered 2-wire transmitters provides seven family groups with a total of 48 transmitter models that interface to a wide variety of voltage, current, temperature, and position measuring devices.

The DSCT 2-wire transmitter conditions and sends analog signals from sensors located in the field to monitoring and control equipment, usually computers, located thousands of feet away in central control areas. The DSCT accepts a wide range of inputs, including millivolt, volt, milliamp, thermocouple, RTD, potentiometer, and slide wire.

It operates on power from a 2-wire signal loop and modulates the supply current to represent the input signal within a 4- to 20-milliamp range. Two-wire transmission loops are very economical methods for connecting sensors to distant control rooms. Since the DSCT operates from the signal loop current, no additional, expensive power and wiring are required. Only low cost, twisted pair wiring is needed.
