Allen-Bradley 1746-NIO4V Analog Output Module

The Allen-Bradley 1746-NIO4V SER A SLC 500 Analog Output Module provides multi-channel analog output capability for precise control of actuators, valves, and proportional devices in SLC 500 systems. Output signals can be configured as analog voltage and/or current, with the channel count defined per model. It is compatible with Allen-Bradley SLC 500 PLCs and I/O racks, and communicates over the backplane bus; the module is rack- or panel-mounted and powered through the SLC 500 rack backplane. Typical applications include manufacturing production lines, process control, water and wastewater treatment plants, HVAC control systems, and material handling environments where reliable analog signal generation improves system responsiveness and process accuracy. The 1746-NIO4V is designed for industrial-rated operating conditions and is installed within a control or PLC enclosure, providing the necessary protection through enclosure-based installation. Common replacements include the 1746-NIO4I Analog Input/Output Module, the 1746-NIO2V Analog Output Module, and the 1734-OA8 Analog Output Compact I/O Module.
