The Allen-Bradley 8500-E151 expansion module is a Series A AC I/O unit designed to extend the I/O capacity of the Allen-Bradley 8500 control family. This digital I/O module is powered by 115 VAC and provides 20 discrete inputs and 12 discrete outputs, enabling direct sensing, switching, and actuation for packaging lines, conveyors, and related automation tasks. As an expansion card, it integrates into an 8500 system to scale I/O without replacing the main controller, delivering a compact, rugged solution for packaging and manufacturing environments.
