Dataforth's DSCT series of loop powered 2-wire transmitters consists of seven family groups with a total of 48 transmitter models that interface to a wide variety of voltage, current, temperature and position measuring devices.
- DSCT 2-wire transmitters condition and send analog signals from sensors located in the field to monitoring and control equipment, usually computers, located thousands of feet away in central control areas
- They accept a wide range of inputs, including millivolt, volt, milliamp, thermocouple, RTD, potentiometer, and slide wire
- They operate on power from a 2-wire signal loop and modulate the supply current to represent the input signal within a 4 to 20mA range
Two-wire transmission loops provide very economical connections between sensors and distant control rooms. Since the DSCT operates from the signal loop current, only low cost, twisted pair wiring is needed.
