Description
Description
The new DRLP Series of loop powered 2-wiretransmitters consists of seven family groups with atotal of 48 transmitter models that interface to a widevariety of voltage, current, temperature and positionmeasuring devices. The DRLP Series providessuperior specifications such as ±0.03% accuracy, fivepoles of filtering, 1500 Vrms continuous isolation, lowoutput noise, and much more.The DRLP Series 2-wire transmitter conditions andsends analog signals from sensors located in the“field” to monitoring and control equipment, usuallycomputers, located thousands of feet away in centralcontrol areas. The DRLP Series accepts a widerange of inputs, including millivolt, volt, milliamp,thermocouple, RTD, potentiometer, and slide wire.It operates on power from a 2-wire signal loop andmodulates the supply current to represent the inputsignal within a 4 to 20-milliamp range.Two-wire transmission loops are very economicalmethods for connecting sensors to distant controlrooms. Since the DRLP Series operates from thesignal loop current, no additional, expensive powerand wiring are required. Only low cost, twisted pairwiring is needed.
DRLP Loop Drive Capability
The DRLP Series transmitter’s wide range of loopsupply voltage (10.8V to 60V) makes it a versatiledevice which can be used in most any current loop. Themaximum loop resistance is determined by subtractingthe transmitter’s minimum loop supply voltage from thetotal loop supply voltage and dividing the result by themaximum loop current (see graph).The low loop supply voltage of 10.8V allows the DRLPto be used in applications with low output powersupplies and the high Loop Supply Voltage of 60V allowsuse in applications with long distance current loops.
