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 or ethernet 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. Handles 100 (ohm), 500 (ohm) and 1000 (ohm) Platinum RTDs with 385 and 392 linearization. A choice of 2-, 3- and 4-wire RTD connections ensures the absolute highest degree of accuracy.

Process Voltage and Current
The iSeries measures process voltage: 0-100 millivolt, 0-1 Volt, 0-10 Volt ranges, and process current: 0-20 mA or 4-20 mA.

iSeries Meter Feature AutoScaling AutoScaling automatically shifts the decimal point right or left depending on the process value of the meter. AutoScaling is active only for temperature reading.

Strain Gauge
The Strain/Process meters and controllers (model "iS") measure inputs from Load Cells, Pressure Transducers, and most any strain gauge sensor. Input ranges include 0 to 100 mVdc, -100 mVdc to 1Vdc and 0 to 10 Vdc in addition to 0-20mA. Built-in excitation bridge transducers, 5Vdc @ 40 mA or 10 Vdc @ 60mA. When communications options are installed, external excitation may be used and ratiometric operation maintained by connecting the external excitation to the sense leads. Both 4 or 6-wire bridge configurations are supported for internal or external excitation. Non-ratiometric operation is also supported for voltage and current transducers. Non-ratiometric operation is also valuable in measuring offset and millivolt output of bridge devices during manufacturing and calibration.
Strain/Process meters and controllers are available in all iSeries Models.

MIL Standard Nickel RTD
Special option for Nickel RTD MIL-T-7990B curve is available as a Factory Setup.

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.

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.

For applications that do not require PID control, iSeries controllers are available in two special models that offer simplified programming. The iSeries “Limit Alarm” model (specify –AL option) is a conventional limit alarm. The iSeries “Simplified Menu” model (specify –SM option) offers simplified programming. The menu flowchart is similar to programmable digital panel meters that are used for on/off control or alarms. (Please see the iSeries operator’s manuals for programming details.)

Built-in Excitation Standard
The Temperature/Process (model “i”) comes standard with built-in excitation (24 Vdc @ 25 mA). This means the same instrument can handle thermocouple, standard RTD’s, or 4-20mA transmitters, with the meter’s built-in excitation. The Strain/Process (model “iS”) comes standard with built-in excitation (10Vdc @ 60mA), 5V excitation is user selectable.
Any excitation voltage between 5 and 24 Vdc is available by special order. Built-in excitation is not available with optional isolated RS-232/ RS-485 serial communications, -C4EI Ethernet option or -DC option.
