The NEWPORT® i8DH and i8DV are high quality, highly accurate single loop Autotune PID Temperature and Process Controllers for 1/8 DIN (96mm x 48mm) horizontal or vertical panel cutouts. Both devices feature the same state of the art technology, uncompromising accuracy, and quality backed by an extended 5-year warranty. The LED’s displaying the Process Value on the i8DH (horizontal 1/8 DIN) are the largest digits of any 1/8 DIN controller. The i8DH and i8DV are ideal controllers for use with transmitters and amplified transducers, are simple to configure and use, while providing tremendous versatility and a wealth of powerful features.
The i8DH and i8DV come standard with your choice of two control or alarm outputs in almost any combination: solid state relays (SSR) rated at 0.5 amp @120/240 Vac; Form “C” SPDT (Single Pole Double Throw) relays rated at 3 amps @120/240 Vac; pulsed 10 Vdc output for use with an external SSR; or Analog Output (0-10 Vdc or 0-20mA) selectable for control or retransmission of the process value.
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. |
The Universal Temperature & Process instrument (model “i“) handles ten common types of thermocouples: K, J, T, E, R, S, B, C, N, and J DIN, multiple RTD’s, and several Process (dc) Voltage ranges: 0-100 millivolt, 0-1 Volt, 0-10 Volt; Process Current range: 0-20 mA. This model also features built-in excitation, 24 Vdc @ 25 mA. with it’s wide choice of signal inputs, this model is an excellent choice for measuring or controlling temperature with a thermocouple, RTD, or 4-20mA transmitter.
The Strain & Process instrument (model “iS“) measures inputs from Load Cells, Pressure Transducers, and most any strain gauge sensor as well as several Process (dc) Voltage ranges: 0 to 100 mVdc, -100 mVdc to 1Vdc and 0 to 10 Vdc; Process Current range: 0-20 mA. The “iS” has built-in excitation of 5 Vdc @ 40mA or 10 Vdc @ 60mA for bridge transducers. This “iS” model supports 4 and 6 wire bridge configurations, ratiometric and non-ratiometric measurements. The “iS” features fast and easy “in-process” calibration/scaling of the signal inputs to any engineering units. This model also features 10 Point Linearization which allows the user to linearize the signal input from extremely nonlinear transducers of all kinds.
The MIL Standard Nickel RTD with MIL-T-7990B curve is available as a Factory Setup.
Ordering Example: iS8DH33-C24-FS (FS: preset for MIL-T-7990B curve, please specify range and accuracy).
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
Any excitation voltage between 5 and 24 Vdc is available by special order. Built-in excitation is not available with optional -C24 isolated RS-232/ RS-485 serial communications, -C4EI Ethernet option or -DC option.
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.)
