The Allen-Bradley 1746-NO4I is a high-performance analog output module designed for the SLC 500 series programmable logic controllers. This module provides four individually isolated analog current outputs, making it ideal for controlling a wide range of industrial devices such as valves, actuators, drives, and chart recorders. It offers precise control with a 12-bit resolution over a 4-20 mA range. The 1746-NO4I easily integrates into any available slot in an SLC 500 chassis, providing a reliable and scalable solution for applications requiring accurate analog signal generation for process control and automation systems.
