PROCESS
INPUTS SIGNAL CONDITIONER
Two models are available, the DRN-PR which provides an analog output that is proportional to the input signal and the DRX-PR which uses a digital RS-485 communication link. Both models can accept unipolar and bipolar signals from 400 mV to 10 Vdc full scale. A 0-20 mA current range is also available. The DRN-PR/DRX-PR also contains a 14 Vdc reference voltage which may be used for transducer excitation. The output of DRN-PR can be user set for 0-10 V, 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-PR 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: ▒0.1% FS Resolution: 11 to 14 bit Excitation: 14 VDC @ 25mA Power Consumption: 2 W (84 Ma @ 24 vDC) without excitation (100 mA @ 24 Vdc), 3 W with excitation (125 mA @ 24 Vdc) Input Ranges: Uni/bipolar, 400 mV to 10 Vdc; 0 to 20 mA full 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-PR digital signal conditioner with RS-485 output for process signals ($275), plus DRN-PS-750 power supply, 115 Vac input, 24 Vdc output @ 750 mA ($130), $275 + 130 = $405. ACCESSORIES
