Key features of the 1746-NO4I module include:

Four isolated analog output channels

Voltage or current output modes for each channel

12-bit resolution, providing 0-10V DC voltage or 4-20mA current output ranges

Fast update rate for real-time control applications

Built-in diagnostics and fault detection capabilities

To use the 1746-NO4I module, it needs to be installed in a compatible Allen-Bradley SLC 500 rack, typically alongside other input and output modules. The module is programmed and configured through the software environment provided by Rockwell Automation, such as RSLogix 500.
