Allen-Bradley 1746-NO8I SLC 500 Analog Output Module 8-Channel Current

Product Introduction

When your SLC 500 system demands precise current output control, the Allen-Bradley 1746-NO8I delivers reliable performance. This analog output module provides eight current output channels, each with a range of 0 to +20 mA. It integrates seamlessly with SLC 500 fixed or modular hardware, making it a versatile choice for upgrading or expanding existing control systems.

Technical Specifications Breakdown

The 1746-NO8I features eight independent current output channels. Each channel supports a 0 to +20 mA output range, ideal for driving actuators, valves, and other analog devices. This module is designed for use with SLC 500 fixed or modular style hardware, ensuring straightforward installation and compatibility.

Industry Applications

In process control environments, the 1746-NO8I excels at regulating flow control valves and variable speed drives. For example, in a chemical processing plant, precise 4-20 mA signals from this module adjust chemical dosing pumps, improving product consistency and reducing waste. Similarly, in water treatment facilities, the module controls chemical feed rates for disinfection and pH adjustment.

Installation & Setup Guidance

Mount the 1746-NO8I into any available slot in your SLC 500 chassis. Ensure the backplane connector aligns correctly before securing the module. Wire each channel using shielded twisted-pair cable to minimize electrical noise. Connect the positive lead to the output terminal and the negative lead to the common return. Configure the output range in your SLC 500 programming software to match your device requirements.

Maintenance & Reliability

Periodically inspect the module for dust accumulation or loose connections. Verify that the ambient temperature remains within the SLC 500 system specifications. The 1746-NO8I is built for long-term reliability in industrial environments, reducing unplanned downtime. Regular system checks help maintain consistent analog output performance.

Selection Guide & Purchasing Advice

Before purchasing, confirm that your SLC 500 system has an available slot and that your power supply can support the module's backplane current draw. The 1746-NO8I is a direct replacement for existing analog output modules in SLC 500 systems. Contact BluePLC Industrial for current availability and pricing.
