DescriptionThe new DRLP 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. The DRLP Series provides superior specifications such as ±0.03% accuracy, five poles of filtering, 1500 Vrms continuous isolation, low output noise, and much more. The DRLP Series 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 DRLP Series 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 DRLP Series operates from the signal loop current, no additional, expensive power and wiring are required. Only low cost, twisted pair wiring is needed.
