The
signal conditioners provide high accuracy isolated measurement of RTD
temperature sensors. For maximum flexibility, the units feature user
configurable RTD types which are fully field scalable.
Two models are available, the DRN-RTD which provides an analog output that is proportional to the input signal and the DRX-RTD which uses a digital RS-485 communication link. Both models can accept 2, 3, or 4 wire 100ohmPT, 500ohmPT and 1000ohmPT RTDs. The output of DRN-RTD can be user set for 0-10V, 4-20 mA or 0-20 mA. Input scaling and configuration of other operating parameters is accomplished by connecting to a standard RS232 port of a personal computer and using the DRN-CONFIG, Windows-based setup software. Once configured the settings may be stored in non-volatile memory and the unit disconnected from the PC. The DRX-RTD is a digital signal conditioner which communicates over an RS-485 communication link. Up to 32 modules may be connected to a single RS-485 port stretching up to 4,000 ft. Through the use of RS-485 repeaters, additional modules may be used and further transmission distances are achievable. SPECIFICATIONS Accuracy at 25░C: ▒0.5░C Input Types: Platinum RTD, 100ohm, 500ohm or 1000ohm element (2, 3 or 4 wire, 385 or 392 curve) Resolution: 0.1░C Power Consumption: 2.4 W (100 mA @ 24 Vdc) Input Range: -200 to 850░C (-328 to 1562░F) DRX Output: 2-wire (half duplex) RS-485 DRN Output: 0 to 10 V @ 10 mA max; 0 to 20 mA or 4 to 20 mA, 10 V compliance To Order (Specify Model No.) Prices Shown in U.S. Dollars
Ordering Example: DRX-RTD digital signal conditioner with RS-485 output for process signals ($250), plus DRN-PS-750 power supply, 115 Vac input, 24 Vdc output @ 750 mA ($130), $250 + 130 = $380. ACCESSORIES
