Allen-Bradley 1746-NO8V Analog Voltage Output Module – SLC 500 Series
Imagine a high-speed bottling line suddenly losing precise fill-level control, or a chemical dosing system outputting unregulated voltage to its actuators — the consequences range from costly product waste to catastrophic process failure. In modern industrial automation, the analog output module is the critical bridge between the controller’s digital logic and the physical world of drives, valves, and positioners. Without a reliable, spec-accurate module like the Allen-Bradley 1746-NO8V, entire production lines grind to a halt.
The 1746-NO8V is Allen-Bradley’s 8-channel analog voltage output module purpose-built for the SLC 500 modular I/O platform — one of the most widely deployed small-to-mid-range PLC families in global manufacturing. Offering ±10V DC output resolution across eight independent channels, this module occupies a trusted position in process control, motion coordination, and drive speed reference applications across automotive, food & beverage, water treatment, and discrete manufacturing industries worldwide.

Key Features & Benefits
- 8 Independent Voltage Output Channels — Simultaneously control up to 8 analog devices from a single module slot, maximizing chassis density and reducing wiring complexity.
- ±10V DC Bipolar Output — Supports both positive and negative voltage references, essential for reversible drive control and servo positioning applications.
- 12-Bit Resolution — Delivers fine-grained output precision for demanding process control loops where coarse steps cause instability.
- Single-Slot Form Factor — Conserves valuable SLC 500 chassis slots, leaving room for expansion as your system grows.
- Direct SLC 500 Backplane Integration — Plug-and-play compatibility with all SLC 500 modular chassis; no external power supply required for the module itself.
- Proven Field Reliability — Designed to Rockwell Automation’s industrial-grade standards, with a track record spanning decades of continuous operation in harsh environments.
Industry & Equipment Applications
- Automotive Manufacturing: Speed reference signals to variable frequency drives (VFDs) on conveyor and assembly lines.
- Food & Beverage: Proportional valve control for liquid filling, mixing ratio regulation, and temperature setpoint output.
- Water & Wastewater Treatment: Pump speed modulation and chemical dosing actuator control.
- Chemical Processing: Continuous process variable setpoint transmission to field instruments and control valves.
- HVAC & Building Automation: Damper actuator positioning and chiller setpoint control integrated with SLC 500 building management systems.
