Product Overview
The 1755-HSC is an Allen-Bradley high-speed counter module in the GuardPLC (Bulletin 1755) platform. It provides two independent high-speed counter channels with associated digital outputs. The module integrates into the GuardPLC 1200 or 2000 distributed I/O system and supports fast counting, encoder and gated modes, with count storage features, suitable for machine safety, motion feedback, and sequential position tracking applications. It enables direct hardware outputs based on count thresholds.
