Dataforth's new DSCT series of loop powered two-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. The DSCT is the latest introduction of Instrument Class® products available from Dataforth, which provide superior specifications such as ±0.03% accuracy, five poles of filtering, 1500Vrms continuous isolation, low output noise, and much more.
The DSCT two-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. |
