Electromagnetic Compatibility



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 to 10 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 EIT-D 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.
Universal foot mount
Mounts to 35 mm DIN rails.

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

Free Active X Controls
Free Active X Controls are provided for the iDRN/iDRX series Signal Conditioners. This free software makes it easy to integrate the "iDRN/iDRX Signal Conditioners" with "Active X Containers" such as Microsoft Visual Basic as well as with popular OLE compliant data acquisition, process control, and industrial automation software from NEWPORT® as well as Wonderware, Intellution, Rockwell Automation, and Object Automation among others.
