Product Description

The Allen-Bradley 1746SC-INO4I is a high-performance isolated analog output module designed for the SLC 500 PLC automation system. Featuring four fully independent isolated output channels, it converts digital control commands from the main controller into standard industrial analog current and voltage signals. It serves as a core signal regulation unit for driving field actuators, control valves and process regulation equipment in industrial process control loops.

Adopting 16-bit high-resolution conversion technology and full-channel electrical isolation design, this module eliminates channel crosstalk and external electromagnetic interference. It supports multi-range analog signal configuration and built-in signal filtering for stable and precise output. With ultra-wide temperature adaptability and industrial rugged design, it ensures 24/7 long-cycle reliable operation for harsh industrial automation and process control scenarios.
