Allen-Bradley 1746-NO8V Detailed Technical Overview
1. Product Overview
The Allen-Bradley 1746-NO8V is an 8-channel analog voltage output module used in the SLC 500 PLC system. It converts digital control signals from the processor into precise analog voltage outputs for industrial field devices.
Each of the eight channels operates independently and can be configured for standard industrial voltage ranges such as ±10 V, 0–10 V, 0–5 V, or 1–5 V depending on system requirements. This makes it suitable for controlling devices that rely on voltage input signals.
The module is widely used in process automation systems where smooth and accurate voltage control is required.
