The iDRN-ST and iDRX-ST signal conditioners provide highly accurate, stable, isolated measurement for strain gage transducers such as load cells, torque transducers, non-amplified pressure transducers, and other bridge based transducers. Both models can accept signals from 30 to 100 mV full scale and provide 10 Vdc reference voltage which may be used for transducer excitation. TWO MODELS: ANALOG or DIGITAL OUTPUTS The iDRN-ST provides an analog output that is proportional to the input signal and the iDRX-ST uses RS-485 Serial Communications. ANALOG OUTPUT MODEL The output of iDRN-ST can be user set for 0 to10 V, 4 to 20 mA or 0 to 20 mA. Input scaling and configuration of other operating parameters is accomplished by connecting to a standard RS-232 port of a personal computer and using the free Windows-based setup software. Once configured the settings may be stored in non-volatile memory and the unit disconnected from the PC. DIGITAL OUTPUT MODEL The iDRX-ST is a digital signal conditioner which communicates over RS-485 communication link using either a simple NEWPORT® ASCII Protocol or MODBUS Protocol. Up to 32 modules may be connected to a single RS-485 port stretching up to 4,000 feet without repeaters. ETHERNET CONNECTION The Optional EIS-2 iServer module can connect up to thirty-two (32) iDRX RS-485 Signal Conditioners to an Ethernet network and the Internet using standard TCP/IP protocol. The iServer can also be used as a simple Serial to Ethernet "bridge" or converter to connect a single iDRN RS-232 device to an Ethernet network and the Internet.
Factory Setup and Configuration at No Extra Charge To make your installation even easier, your iDRN (Analog Output and RS-232) signal conditioners can be ordered preconfigured by the factory at no extra charge. You select the input types, ranges and output scale and we will program the instruments to your specific requirements in our calibration lab prior to shipment. For custom factory setup and scaling of the iDRN model, please specify the “-FS” option. Please Specify: Input Value High & Low Output Value High & Low Excitation: 10 or 14 Volts dc Ratiometric or Non-Ratiometric Example: 0 V = 4 mA, 100 mV = 20 mA, Excitation 10 V, Ratiometric
Accuracy at 25°C: ±0.2% FS Resolution: 13 to 15 bit Excitation: 10 V @ 30 mA Power Consumption: 2 W without excitation (100 mA @ 24 Vdc), 3 W with excitation (125 mA @ 24 Vdc) Input Ranges: 0 to 30 to 0 to 100 mV full scale iDRX Output: 2-wire (half duplex) RS-485 (NEWPORT® ASCII Serial Protocol and MODBUS Serial Protocol) iDRN Output: 0 to 10 V @ 10 mA max; 0 to 20 mA or 4 to 20 mA, 10 V compliance Strain Default settings iDRN: Input 0-20 KHz; Output 4-20 mA (Custom Settings available at no charge.) To Order (Specify Model No.) Prices Shown in U.S. Dollars
Ordering Example: iDRX-ST digital signal conditioner for strain gages and bridge transducers with RS-485 output ($300), plus CAT-285 bi-directional RS-232-RS-485 converter for iDRX series ($148), $300 + 148 = $448. ACCESSORIES
