Product Description
The Allen-Bradley 8-Channel Analog Output Module is a high-performance I/O module designed for use in CompactLogix and ControlLogix systems. It provides eight analog output channels capable of converting digital signals from the PLC into precise analog voltage or current signals. This module is ideal for controlling devices such as actuators, drives, valves, and other field instruments that require smooth and accurate analog control.
