Allen-Bradley 8600-1726L Programmable Logic Controller Module

Allen-Bradley 8600-1726L is a digital I/O module that provides 32 inputs and 32 outputs, delivering 64 discrete digital I/O points in a single plug‑in card for industrial control. Built for use with Allen-Bradley 8600‑series CNC controllers and compatible PLC backplanes, it appears in supplier catalogs as a 32‑in/32‑out I/O expansion device that supports digital sensing and actuation across automation cabinets and CNC equipment. In Osai‑based AB system listings the part is associated with OS‑5550/OS‑5551 designations, reflecting its role in AB/OSAI integration scenarios. Typical applications include reading limit switches and other digital sensors (inputs) and driving relays, motor starters, or other actuators (outputs) to coordinate machine tools, conveyors, and automated machinery. The model is described across distributors as a 32‑input/32‑output I/O module that integrates with Allen‑Bradley PLCs and related backplane interfaces used in legacy industrial control architectures.
