Built for temperature, process-limit, and alarm duties, this 1/32 DIN controller takes universal thermocouple, RTD, and analog voltage or current inputs and drives two SPDT relay outputs. It operates on 12 to 36 V DC and reads out on a single 4-digit color LED display. Best for over-temperature safety cutoffs on ovens, furnaces, and process lines.

The OMEGA(R) iSeries Limit Controller offers unparalleled flexibility in process measurement and alarm applications, accepting 10 different thermocouple types, 18 RTD combinations or 4 process voltage/current inputs and providing 2 relay alarm outputs and a large multi-color, programmable display.
Easily configured options include 11 different alarm conditions and the unit supports an external reset input and a buzzer audio annunciator. Front panel configuration buttons allow the user to select the type of input, the alarm conditions and the resulting display color.
Process inputs are fully scalable, supporting virtually all engineering units with a selectable decimal point providing a perfect solution for pressure, flow or other process inputs.
