Omega StrongSame Quality Product – New Name!
We’re building a stronger, unified brand so we can provide you with the best products in the industry. To do this, the Newport branded products will now be Omega branded starting July 15, 2018. You can expect the same support and quality as always, and of course the same features and specs, just with a new part number and logo. Please refer to iSeries products, CNi-AL Limit Controller at for details.

The NEWPORT® iSeries Limit Alarm 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.

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.
