The Allen-Bradley 1746-NO8I SLC 500 Analog Current Output Module is an industrial PLC I/O module used in the Allen-Bradley SLC 500 automation system to provide precise analog current outputs. It offers eight independent current output channels (typically 0–20 mA or 4–20 mA ranges) for controlling field devices such as valves, actuators, drives, and transducers. The module supports high-resolution 16-bit output, fast update and response times, and multiple data formats (including scaled engineering units and PID scaling), making it suitable for process-control and analog control applications. It installs in any SLC 500 chassis slot (except slot 0) and integrates with RSLogix 500 software for configuration and monitoring.
