NEW Controllers and Signal Conditioners with Embedded Internet

OMEGA extremely accurate instruments for DIN rail mounting. The compact iDR Series signal conditioners and PID controllers are available with OMEGA’s award-winning “embedded Internet” technology. With the Ethernet option, the instruments connect directly to a LAN and can even serve Web pages over the Internet. The devices are easily configured with a handheld programmer iDRP, or from a computer with an Ethernet, RS232, or RS485 connection. The universal signal input covers 10 thermocouple types; 100 and 1000 Ω RTDs with 2-, 3-, or 4-wire connections; and process (DC) voltage, current, and strain gage inputs. Optional outputs include form “C” SPDT relays, SSRs, DC pulse, programmable isolated or non-isolated analog voltage, and current.

The innovative OMEGA®DIN rail iSeries devices feature state-of-theart technology, uncompromising

introduces a family of

accuracy, and quality backed by a 5-year warranty. The DIN rail iSeries family includes extremely accurate signal conditioners and single-loop PID controllers that are simple to configure and use, while providing tremendous versatility and a wealth of powerful features.

Embedded Internet and Serial Communications

Featuring optional "embedded Internet" (specify “-EI” option), the iSeries devices connect directly to an Ethernet network and transmit data in standard TCP/IP packets. They even serve Web pages over a LAN or the Internet. The iSeries also features serial communications. With the “-C24” option, the user can select from the optional remote programmer menu between RS232, RS422, and RS485, with straightforward ASCII commands or MODBUS.

iSeries Family

The OMEGA family of microprocessor-based instruments offered in 3 sizes. The instruments have a similar setup and configuration menu and method of operation, which is a tremendous time saver for integration of a large system.

Quality and Technology

The iSeries packs a wealth of power and features into the smallest of packages, employing COB (chip-onboard) and SMT (surface mount technology) assembly techniques and automation. Every iSeries instrument is thoroughly calibrated and tested at several stages during production. The iSeries offers very high accuracy for industrial instrumentation: 0.03% of reading. The analog-to-digital conversion uses a proprietary 20-bit ASIC (application-specific integrated circuit), patented algorithms, and smart filtering.

Universal Inputs

The iSeries instruments offer a broad selection of signal inputs. The choices are easily selected from the remote programmer menu with 4 front-panel pushbuttons, or by serial or Ethernet communications.

Ten Thermocouple Types

The iSeries handles 10 thermocouple types: K, J, T, E, R, S, B, C, N, and J DIN. The patented thermocouple linearization algorithms employed in the iSeries uphold the highest standards of accuracy.

Most Accurate RTD Measurements

The iSeries works with a wide selection of RTDs and produces the most accurate RTD measurements. It handles both Pt 0.00385 and

0.00392 curves; and 100 Ω, 500 Ω, and 1000 Ω. A choice of 2-, 3-, and 4-wire RTD connections ensures a high degree of accuracy.

Process Voltage and Current

The iSeries measures process voltage: 0 to 100 mVdc, 0 to 1 Vdc, 0 to 10 Vdc ranges, and process current: 0 to 20 mA.

Strain Gage

The strain/process (iSDR) instruments measure inputs from load cells, pressure transducers, and most strain gage sensors, as well as process voltage and current ranges. Input ranges include 0 to 100 mVdc, -100 mVdc to 1 Vdc, and 0 to 10 Vdc, in addition to 0 to 20 mA. The iSDR supports 4- and 6-wire bridge configurations, and ratiometric and non-ratiometric measurements. The iSDR features fast and easy “in process” calibration/scaling of the signal inputs to any engineering units. It also features 10-point linearization, which allows the user to linearize the signal input from extremely non-linear transducers of all kinds.

Built-In Excitation Standard

The temperature/process models (iDR and iDRA) come with built-in excitation (24 Vdc @ 25 mA). Any excitation voltage between 5 and 24 Vdc is available by special order. With built-in excitation the same instrument can handle thermocouples, standard RTDs, or 4 to 20 mA transmitters. The strain/process model (iSDR) comes with a built-in excitation, of 10 Vdc @ 60 mA; 5 Vdc @ 40 mA excitation is user selectable. Built-in excitation is not available with the RS232/RS485 serial communications or DC power options.

Control Functions

The iSeries offers either simple manual on/off operation or 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 is during start-up. Maximum ramp time is

99.59 (HH.MM); soak, 00.00 to

99.59 (HH.MM); and damping, 1 to 8 in unit steps. For those who only need simplified menus and no PID control, a limit alarm (-AL) option is available.

Control or Alarm Outputs

Users have a choice of 2 control or alarm outputs in almost any combination: solid state relays (SSRs) rated at 0.5 A @ 120/240 Vac; form “C” SPDT (single pole, double throw) relays rated at 3 A @ 120/240 Vac; and pulsed 10 Vdc output for use with an external SSR.

Analog Output

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

Optional Remote Programmer/ Color Display

The remote programmer/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, in AMBER to signal the normal operating range, and in RED to signal an alarm condition. The changes in color are easily seen from a distance, and machine operators can react quickly to changing conditions. 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 3 separate locations, or to display 3 different measurements, such as temperature, pressure, and flow.
