Built for closed-loop PID control, this 1/16 DIN controller takes universal thermocouple, RTD, analog, and strain-gauge inputs and drives solid-state relay outputs. It operates on an AC supply, reads out on a dual 4-digit color LED display, and connects via EtherNet/IP. Best for oven, furnace, and extruder temperature regulation.

The OMEGA(R) iSeries is a family of microprocessor-based instruments offered in three true DIN sizes. 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.
The iSeries family includes extremely accurate digital panel meters "DPi" and single loop PID controllers "CNi" that are simple to configure and use, while providing tremendous versatility and a wealth of powerful features. The CNi Series covers a broad selection of transducer and transmitter inputs with 2 input models.
The strain and process instruments (CNiS models) measure inputs from load cells, pressure transducers, and most any strain gage sensor as well as process voltage and current ranges.
This CNiS model supports 4- and 6-wire bridge communications, ratiometric measurements. The CNiS 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 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.
The iSeries are 1/8, 1/16 and 1/32 DIN controllers featuring the big iSeries color-changing display. The digits are twice the size of typical 1/8 DIN panel meters. The iSeries feature the only LED displays that can be programmed to change color between GREEN, AMBER, and RED.
Featuring optional "embedded Internet" the iSeries connect directly to an Ethernet network and transmit data in standard TCP/IP packets, or serve Web pages over a LAN or the Internet. The iSeries are also available with serial communications. The user can select from the pushbutton menu between RS232, RS422, and RS485, with straightforward ASCII commands or MODBUS.
