i-Series 1/32, 1/16, 1/8 DIN Programmable Temperature/Process Meters with RS232 & RS485 Communications Standard

----------------------------

Manufacturer: Omega(USA)

Model: DPi Series

Introduction: 

     The innovative OMEGA^® iSeries of meters/controllers combines in one intelligent industrial instrument features of an extremely accurate digital panel meter and a fully functional PID controller. The OMEGA iSeries instruments are simple to configure and use, while providing tremendous versatility and a wealth of powerful features.

     i/8, i/16, i32 FAMILY
     The OMEGA^® iSeries is a family of microprocessor-based instruments offered in three true DIN sizes with NEMA-4, IP65 rated front bezels. All of the instruments share the same set-up and configuration menu and method of operation, a tremendous time saver for integration of a large system.

     Programmable Color Display
     The OMEGA^® i/8, i/16, and i/32 are the first complete series of 1/8, 1/16 and 1/32 DIN process control instruments with totally programmable color displays. The display can be programmed to change color at any setpoint or alarm point. For example, the instrument can be programmed to display the Process Value in GREEN during warm-up, switching to AMBER to signal the normal operating range, and in RED to signal an alarm condition. The changes in color are quickly seen from a distance, and machine operators can intuitively react to changing conditions.

     In another example, the instrument can be programmed to display GREEN for normal, AMBER to signal a minor alarm condition, and RED for a major alarm. The colors can be programmed to change back when the value drops back below the alarm point or to "latch" on until being reset by the operator.

    The instrument can also be programmed to display only one unchanging color: GREEN, AMBER, or RED. This is a useful way to let an operator identify, at a glance, process values in three separate locations, or to display three different measurements such as Temperature, Pressure, and Flow.

     Designed and Manufactured in the USA
     The innovative OMEGA^® iSeries of meters/controllers features an extended Five (5) YEAR warranty at no extra charge. The iSeries packs a wealth of power and features into the smallest of packages, utilizing COB (chip-on-board) and SMT (surface mount technology) assembly techniques and automation. Every iSeries instrument is thoroughly calibrated and tested at several stages throughout production. The iSeries offers the highest accuracy for industrial instrumentation at 0.03% of reading. The analog-to-digital conversion utilizes proprietary 20-bit ASIC (application specific integrated circuit) patented algorithms and smart filtering.

     Universal Inputs
     The innovative iSeries offers the broadest selection of signal inputs available on one industrial instrument. The choices are easily selected from the Menu with four front panel pushbuttons, or by serial communications.

10 Thermocouple Types The iSeries handles TEN (10) thermocouple types: K, J, T, E, R, S, B, C, N, and J DIN. The patented thermocouple linearization algorithms employed in the iSeries produce the highest standard of accuracy.

      Most Accurate RTD Measurements
    The iSeries works with the widest selection of RTD’s and produces the most accurate RTD measurements. Both Pt 0.00385 and 0.00392 curves. 100 (ohm), 500 (ohm) and 1000 (ohm). A choice of 2-, 3- and 4-wire RTD connections ensures the absolute highest degree of accuracy.

     Process Voltage and Current
     The OMEGA^® iSeries measures process voltage: 0-100 millivolt, 0-1 Volt, 0-10 Volt ranges, and process current: 0-20 mA.

     Analog Output
     The optional analog output can be programmed within a range of 0-10 Vdc or 0-20 mA. It is selectable as either a control output or as a calibrated retransmission of the process value-a unique feature among controllers.

      Built-in Excitation Standard
     The iSeries comes standard with built-in 24 Vdc @ 25 mA excitation for transmitters or other devices. This means the same instrument can handle thermocouples, RTD’s, and 4-20 mA transmitters, with its own excitation. (Built-in excitation is not available with optional Isolated RS-232/RS-485 Serial communications.)

     Control Functions
     The iSeries can control simple manual operation to ON-OFF and full Autotune PID control. (Selectable preset tune, adaptive tune, PID, PI, PD control modes.) The dual control outputs can be configured for a variety of independent control and alarm applications such as heat/heat, heat/cool, heat/alarm, cool/cool, cool/alarm or alarm/alarm. The ramp-to-setpoint feature allows the user to define the rate of rise to setpoint, minimizing thermal shock to the load during start-up. Maximum ramp time: 99.59 (HH.MM), Soak: 00.00 to 99.59 (HH.MM), Damping: 1 to 8 in unit steps. Input types: J, K, T, E, R, S, B, C, N, J-DIN, RTD 100 ohm, 500 ohm & 1k ohm in 0.00385 or 0.00392, 0 to 20 mA, 0 to 100 mV, 0 to 1 V and 0 to 10 Vdc.

Free Software      Free interface software is provided for easy set-up, configuration and data acquisition with the OMEGA® iSeries. (Picture at right is an example of software that might be used).

        Free ActiveX Controls
      Free ActiveX Controls are provided for the iSeries, making it easy to integrate the iSeries 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^®, GE Fanuc, Intellution, Rockwell Automation, Object Automation, iconics, and Wonderware among others.

      Optional Isolated RS-232 and RS-485 Serial Communications
      The iSeries are the first intelligent industrial instruments to offer both RS-232 and RS-485 serial communications in one instrument which can be selected from the menu.

      The iSeries features both the OMEGA serial protocol and MODBUS serial protocol.

      Free Factory Setup and Configuration
      Make installating your iSeries meter or controller easier by ordering it preconfigured by the factory, at no extra charge. You specify the input types, scaling if applicable, set points, alarm points, etc. and we will program the instruments to your specific requirements in our calibration lab prior to shipment. For a checklist of factory setup parameters, please consult your OMEGA^® applications engineers.. The Factory Setup and configuration option requires the serial communication "-C24" option.

      Custom Configurations
      Custom color bezels and enclosures are available for Original Equipment Manufacturers. Enhance the appearance of your equipment design with custom colors. Consult the OMEGA^® OEM Group. i Series LED displays are considerably bigger, brighter and therefore more visible than displays for conventional instruments with the same DIN size. The segments in the i/8 are 21 mm (.83") high.
