The 1746-NIO4I by Allen Bradley is an analog combination module in the SLC 500 series. This module has four total analog channels; in a single slot module, it has two (2) inputs and two (2) outputs with a common voltage mode of -20 to 20 Volts. 

The common rejection module signal at 60 Hertz is 105 dB; its normal rejection mode signal at 60 Hertz is 55 dB. Its backplane current draw at 5 Volts is 55 mA, whereas with 24 Volts, it increases to 145 mA. This module must receive both 5 and 24 Volts of power from the backplane source of the SLC 500 setup; some similar modules may require an external power source, but the 1746-NIO4I will not work with one.

The 1746-NIO4I contains two (2) current (or voltage) inputs that can be selected by the user per each channel, as well as two (2) current outputs.

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!
