About the Allen-Bradley 1746-NO8V

The 1746-NO8V is an SLC 8 point analog voltage output module, now discontinued. Its eight outputs cover ±10.25V DC with a maximum load current of 10 mA. Overall accuracy is 0.1% of full scale at 25 °C and 0.2% at 60 °C, with non-linearity of 0.06% of full scale. It draws 120 mA at 5V and 160 mA at 24V from the backplane.

What is the 1746-NO8V used for?

It sends eight voltage signals from an SLC 500 controller, converted by an R-2R ladder network. The typical update time for all 8 channels is 5 ms in Class 1 and 10 ms in Class 3.

Lifecycle and successor

Discontinued (Rockwell Automation lifecycle status, checked 24 October 2026).
