The Spectrum Controls 1756SC-IF8U is a 1756 ControlLogix compatible universal analog input module. This module is an encompass partner manufactured module that features eight (8) analog input channels configurable for Thermocouple (J, K, T, B, E, R, S, N, C), Resistance Temperature Detector (RTD) (PT385/3916, Ni618/672, NiFe518, Cu426), Resistance (0-150, 0-1000, 0-3000 ohms), Current (0-20 mA, 4-20 mA), and Voltage (±50 mV, ±100 mV, 0-5 V, 1-5 V, 0-10 V, ±10 V) input channels.

For the 1756sc-IF8U, the communication is usually more efficient with any potential burden on the controller lessened. The integration with other products has also been improved. The 1756sc-IF8U supports removal-and-insertion of modules under power (RIUP) enabling an easier, faster and more efficient maintenance with little interference to the application process. The environmental conditions for the 1756sc-IF8U include operation temperatures between 0 and 60 degrees Celsius with storage temperatures of -40 to 85 degrees Celsius. The relative humidity for the 1756sc-IF8U is 5 to 95% non-condensing.

The 1756sc-IF8U is a universal analog input module that is manufactured by Spectrum Controls, an Allen-Bradley encompass partner company. Spectrum controls manufactures Logix compatible modules such as I/O and communication modules. The 1756-IF8U specifically offers capability of accepting a wide variety of inputs signals for measurement of different process variables. Compatible inputs signals are Voltage, Current, Resistance, Thermocouple, and Resistance Temperature Detector (RTD).

Picture/ Video Request

Buying equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to buy equipment aboard and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.

With video, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

Request to for the video to view the actual piece of equipment you're interested in before purchasing. You can in close to see the labels with the serial number or  the overall condition of the equipment.

It's like having the store come to you!
