Product Introduction

The Allen-Bradley 1746-NO8I is an analog output module designed for the SLC 500 programmable controller platform. It provides precise current output signals for controlling field devices, making it suitable for applications requiring stable and accurate analog control.

This module features 8 analog output channels, each capable of delivering 0–20 mA current signals. It is typically used to drive actuators, control valves, variable frequency drives, and other process control equipment. The module converts digital values from the PLC into proportional current outputs, enabling smooth and continuous control of industrial processes.

With 16-bit resolution, the 1746-NO8I ensures high output accuracy and fine control granularity. Its plug-in connection design simplifies installation and maintenance, while its compatibility with the SLC 500 system allows easy integration into existing automation architectures.
