A-B 1769-HSC/A High Speed Counter Module

Product Description

Allen-Bradley 1769-HSC/A is a CompactLogix High-Speed Counter Module manufactured by Rockwell Automation. It is designed to provide high-speed counting and encoder feedback functions for CompactLogix 1769 Compact I/O systems. The module supports high-frequency pulse counting applications such as encoder position tracking, speed measurement, and production counting.

The module provides 2/4 channel high-speed counter and encoder capability, allowing CompactLogix controllers to process fast input signals that standard digital input modules cannot handle.
