RTD
SIGNAL CONDITIONER
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
