1746-NO4I Functional Description

The Analog Output Module Allen-Bradley 1746-NO4I  is a 4-channel analog output module designed for the SLC 500 programmable controller system, delivering precise current control signals for industrial automation applications. This Allen-Bradley 1746-NO4I Analog Output Module provides non-isolated 0-20mA/4-20mA outputs with 16-bit resolution, ensuring accurate signal generation for process control systems. Operating on 24VDC power with a 55mA @ 5VDC current draw, the Allen-Bradley 1746-NO4I is engineered for reliable performance in demanding factory environments while maintaining compatibility with the complete SLC 500 I/O family.

As part of Rockwell Automation's comprehensive analog I/O offering, the Analog I/O Modules 1746-NO4I AB specializes in current output applications, complementing the voltage-output NO4V module and combination NIO4I/NIO4V modules in the series. The Allen-Bradley 1746-NO4I delivers dedicated output functionality compared to the fast-sampling FIO4I/FIO4V modules, making it ideal for standard-speed control applications requiring consistent current signal generation. Its compact single-slot design optimizes control cabinet space while providing four independent output channels for flexible system configuration.

The 1746-NO4I ROCKWELL PLC MODULE serves critical roles in industrial processes requiring precise analog control, including valve positioning, variable speed drive control, and proportional system regulation. Its non-isolated architecture provides cost-effective solutions for applications where channel-to-channel isolation isn't mandatory, while still maintaining signal integrity through advanced noise reduction circuitry. The module's robust construction ensures reliable operation in typical manufacturing conditions, supporting continuous process control in industries ranging from chemical processing to material handling.

Engineered for easy integration, the Allen Bradley 1746-NO4I IN STOCK features straightforward configuration through Rockwell's RSLogix 500 programming software, allowing quick setup and troubleshooting. Its design emphasizes maintenance-friendly operation with clear status indicators and durable terminal connections that withstand vibration and temperature fluctuations common in industrial environments. As part of the proven SLC 500 system, this output module continues to support legacy automation installations while delivering the precision and reliability expected from Allen-Bradley control components.
