About the Allen-Bradley 1746-NIO4V
The 1746-NIO4V is an SLC 4 point analog voltage combination module, now discontinued. It has 2 inputs at 16 bit resolution with sigma-delta modulation and a 60 ms step response; the current input range is ±20 mA nominal, ±30 mA maximum. The output range is ±10V DC minus 1 LSB, and backplane isolation withstands 500V AC and 710V DC for 1 minute.
What is the 1746-NIO4V used for?
It handles analog inputs and ±10V DC outputs in a single SLC 500 slot (selection guide 1747-SG001). Output load current is 10 mA maximum.
Lifecycle and successor
Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
