About the Allen-Bradley 1746-NO4V

The 1746-NO4V is an SLC 4 point analog output module, discontinued on 12/30/2015. Its 4 outputs have a full scale of 10V DC and a normal range of ±10V DC -1 LSB, from a 14-bit R-2R ladder converter (selection guide 1747-SG001). Normal step response is 2.5 ms, maximum load current is 10 mA and overall accuracy is ±0.384% of full scale. It draws 55 mA at 5V and 145 mA at 24V from the backplane.

What is the 1746-NO4V used for?

It sends four voltage signals from an SLC 500 controller. Output coding is -32,768 to +32,764 for ±10V DC, a resolution of 1.22070 mV per LSB. Isolation is tested at 500V AC and 710V DC for 60 seconds.
