The iD Series signal conditioners combine the accuracy of laboratory instrumentation with the performance required by demanding industrial applications. The iD Series signal conditioners are ideal for those applications in Data Acquisition, Test & Measurement, Process Control, and Industrial Automation where accuracy, performance, and reliability are critically important.

The iD Series signal conditioners mount on a 35mm DIN rail, and operate on any voltage between 10 to 32 DC power. (A matching 24 Vdc 850 mA switching power supply is also available.) The devices feature three-way isolation of up to 1800 Vdc between the signal inputs, outputs, and power supply.

The iD series feature seven (7) models designed for each of the most widely measured signal inputs: Process (DC) Voltage and Current; Strain Gage; Thermocouples; RTD’s; AC Voltage; AC Current; Frequency/Pulse.

The iD series devices are designed to work directly with a variety of sensors and transducers; no other components are necessary. For sensors such as RTD’s, strain gages, and some process transducers, precise stable excitation is provided directly from the iD module.

The iD series are available with two different types of signal outputs: Analog or Digital. The iDRN series provides a totally scalable analog output in DC voltage or current. The iDRX series provide a digital RS-485 output. Both iD Series signal conditioners are intelligent microprocessor based instruments that can be scaled and programmed by computer via serial communications, or over an Ethernet network.

iDRN Series Analog Output

The iDRN series feature a 0 to 10 Vdc, or 0 to 20 mA (including 4 to 20 mA) analog output signal that is typically scaled to be directly proportional to the input signal. It is an ideal component in a system with PLC’s or PC’s with analog data acquisition boards.

The iDRN series are an excellent choice for applications that demand an extra measure of accuracy and performance that is not possible with conventional “analog” signal conditioners or transmitters. Unlike conventional analog devices that are scaled by adjusting zero and span “pots”, the programmable, micro-processor based iDRN instruments are scaled precisely on a PC with free and simple Windows software. The iDRN modules connect directly to a PC’s RS232 Serial Communications port for programming and scaling.

Once the module is conﬁgured, the parameters are saved in nonvolatile memory. The device can be disconnected from the PC, or the RS232 output from the module can be used for continuous data acquisition in addition to the analog output.

Alternatively, the iDRN signal conditioner can be connected to a PC’s Ethernet port or an Ethernet network using the EIT module as a Serial/Ethernet bridge.

Free Setup and Conﬁguration

If an iDRN signal conditioner is not going to be connected to a computer, it can be ordered preconﬁgured by the factory at no extra charge. The user can select the input types, ranges and output scale, and OMEGA will program the instruments to those speciﬁc requirements in our calibration lab prior to shipment. For custom factory setup and scaling of the iDRN model, please specify the “-FS” option.

iDRX Series Digital Output

The iDRX Series Signal Conditioners provide highly accurate digital outputs. Each module provides an RS-485 Serial output that can be transmitted directly to computers and other devices with serial communications capability, or converted to Ethernet.

On an RS-485 bus, up to 32 modules can be connected over a distance of 1200 m (4000') on a single pair of wires. With optional RS-485 repeaters, up to 254 modules may be connected to a single RS-485 port. The iDRX Series digital conditioners may be connected to an RS-485 bus using either screw terminator or RJ-12 connector.

ASCII and MODBUS

The user can select between an easy-to-use, straightforward ASCII protocol, or the popular MODBUS protocol found in many existing industrial installations. With the simple ASCII commands, writing programs using the iDRX does not require special drivers or libraries. In addition, many off-the-shelf software packages can be used with the iDRX devices without any programming. OMEGA also provides a number of useful programs and demos for the iDRX at no charge.

OPC Server And Active X Controls

OMEGA offers an optional OPC Server (OLE for Process Control) and ActiveX Controls for the iDRX Series. These programs make it easy to integrate the iDRX devices with information systems using “ActiveX Containers” such as Microsoft Visual Basic and Microsoft Excel as well as with popular OLE and OPC compliant data acquisition, process control, and industrial automation software from OMEGA, Iconics, Wonderware, Intellution, Rockwell Automation, and GE Fanuc Cimplicity among others.

Ethernet and Internet

The iDRX signal conditioner can also be connected to an Ethernet network using the EIT module as a Serial/Ethernet bridge. One EIT module can be a hub for up to 32 iDRX modules. The EIT module packages the ASCII serial communications in standard TCP/IP Protocol for transmission over standard Ethernet networks and the Internet. Unlike some manufacturer’s products this system uses totally open, nonproprietary standards and protocols for Ethernet and Internet. The user can integrate these devices with any commercial or industrial grade networking components that also comply with the popular international standards.

iServer EIT

The OMEGATM EIT “iServer” is a DIN rail device which can connect up to 32 iDRX RS-485 instruments to an Ethernet network and the Internet using standard TCP/IP protocol. It 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. (RS-232 Serial Communications are limited to a single connection between two devices, such as one computer and one signal conditioner. RS-485 is limited to 32 devices on a communications bus per hub or repeater).

The “iServer” is a Web Server as well as an Ethernet-Serial bridge and Hub for up to 32 RS-485 devices. The OMEGA

iServer is also compatible with the OMEGATM iSeries Controller and Meters, the DP41 family of ultra high performance digital panel meters, and the MICROMEGATM series of Temperature and Process controllers.

Each “iServer” is assigned an IP address on the Ethernet network and can also be assigned an easily remembered name. In fact, the device could be assigned an authorized Internet IP address from an Internet Service Provider and function as a World Wide Web Server delivering whatever speciﬁc information is called for.

The iDRN and iDRX Series signal conditioners provide highly accurate, stable and isolated measurement of AC voltage and current signals across extremely wide ranges: AC Current ranges from 0 to 10 mA through 0 to 5 A ac; AC Voltage ranges from 0 to 400 mV to 0 to 400 Vac.

Analog or Digital Outputs

The iDRN-ACV and iDRN-ACC accept ac voltage and ac current respectively and provide an analog output which is proportional to the input. The iDRX-ACV and iDRX-ACC accept ac voltage and ac current respectively and transmit via RS-485 Serial Communications.

Analog Output Model

The Analog Output models can be conﬁgured for outputs of 0 to 10 Vdc,

or by Ethernet with the optional EIT module. Once conﬁgured the settings are stored in non-volatile memory and the unit can be disconnected from the PC.

Factory Setup and Conﬁguration at No Extra Charge (iDRN Analog Output Modules)

Please Specify:

iDRN‑ACV: Input value high and

low; output value high and low

Example: 0 volts = 4 mA,

400Vac = 20 mA

iDRN‑ACC: Input value high and

low; output value high and low

Example: 0 A = 4 mA, 5 A = 20 mA

Digital Output Model

The iDRX-ACC (Current) and iDRX-ACV (Voltage) communicate via RS-485 Serial Communications using either simple ASCII Commands or the popular MODBUS Protocol. Up to 32 modules may be connected to a single RS-485 port stretching up to 1200 m (4000'), more with RS-485 repeaters.
