Description
Description
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 10-32 DC power. (A matching 24 Vdc 850 mA switching power supply is also available.) The devices feature three-way isolation of up to 1800 V between the signal inputs, outputs, and power supply.
The iD series feature seven (7) models designedfor each of the most widelymeasured signal inputs: Process(DC) Voltage and Current; StrainGage; Thermocouples; RTD's; AC Voltage; ACCurrent; Frequency/Pulse. TheiD series devices are designed towork directly with a variety of sensorsand transducers; no other componentsare necessary. For sensorssuch as RTD's, straingages, and some processtransducers, precise stableexcitation is provided directly fromthe iD module.
The iD series are available with twodifferent types of signal outputs:Analog or Digital. The iDRN seriesprovides a totally scalable analogoutput in DC voltage or current.The iDRX series provide a digitalRS-485 output. Both iD Seriessignal conditioners are intelligentmicroprocessor based instrumentsthat can be scaled and programmedby computer via serialcommunications, or over anEthernet network.
iDRN SERIES ANALOG OUTPUT
The iDRN series feature a 0-10 Vdc,or 0-20 mA (including 4-20 mA)analog output signal that is typicallyscaled to be directly proportional tothe input signal. It is an idealcomponent in a system with PLCsor PC's with analog dataacquisition boards.
The iDRN series are an excellent choicefor applications that demand anextra measure of accuracy and performancethat is not possible withconventional "analog" signal conditionersor transmitters. Unlike conventionalanalog devices that arescaled by adjusting zero and spanpots, the programmable, micro-processorbased iDRN instrumentsare scaled precisely on aPC with free and simple Windows software.The iDRN modules connectdirectly to a PC's RS-232Serial Communications port forprogramming and scaling.Once the module is configured,the parameters are saved in nonvolatilememory. The device canbe disconnected from the PC, orthe RS-232 output from the modulecan be used for continuous dataacquisition in addition to theanalog output.
Alternatively, the iDRN signal conditionercan be connected to a PC's Ethernet port or an Ethernetnetwork using the EIT-D module as aSerial/Ethernet bridge.
FREE SETUP and CONFIGURATION
If an iDRN signal conditioner is notgoing to be connected to acomputer, it can be orderedpreconfigured by the factory at noextra charge. The user can selectthe input types, ranges and outputscale, and trodeks will program theinstruments to those specificrequirements in our calibration labprior to shipment. For customfactory setup and scaling of theiDRN model, please specify the-FS option.
iDRX SERIES DIGITAL OUTPUT
The iDRX Series SignalConditioners provide highlyaccurate digital outputs. Eachmodule provides an RS-485 Serialoutput that can be transmitteddirectly to computers and otherdevices with serial communicationscapability, or converted to Ethernet.On an RS-485 bus, up to 32modules can be connected over adistance of 1200 m (4000 ft) on asingle pair of wires. With optionalRS-485 repeaters, up to 254modules may be connected to asingle RS-485 port. The iDRXSeries digital conditioners may beconnected to an RS-485 bus usingeither screw terminator or RJ-12connector.
ASCII AND MODBUSThe user can select between aneasy-to-use, straightforward ASCIIprotocol, or the popular MODBUSprotocol found in many existingindustrial installations. With thesimple ASCII commands, writingsprograms using the iDRX does notrequire special drivers or libraries.In addition, many off-the-shelfsoftware packages can be usedwith the iDRX devices without anyprogramming. trodeks alsoprovides a number of usefulprograms and demos for the iDRXat no charge.
OPC Serverand ACTIVE XCONTROLS
trodeks offers anoptional OPC Server(OLE for ProcessControl) and ActiveXControls for the iDRXSeries. Theseprograms make iteasy to integrate theiDRX devices withinformation systemsusing ActiveContainers such asMicrosoft Visual Basicand Microsoft Excel aswell as with popularOLE and OPCcompliant dataacquisition, processcontrol, and industrialautomation software fromtrodeks®, Iconics, Wonderware,Intellution, Rockwell Automation,and GE Cimplicity among others.
