*For our newest range of meters and controllers with Modbus connectivity, expanded ramp and soak programs, universal inputs, and simple PC set-up, visit our Platinum Series.*

The OMEGA™ 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 3-colour display that can change colour on alarm.

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 colour. Process inputs are fully scalable, supporting virtually all engineering units with aselectable decimal point providing a perfect solution for pressure, flow or other process inputs. Standard features include a built-in 24 Vdc excitation source for transmitters or other devices and a universal power supply that accepts 90 to 240 Vac. A low power option is available that supports 24 Vac or 12 to 36 Vdc.
