Description

Product Description

The IC695HSC304 is a dedicated high-speed counting module for the GE Fanuc / Emerson PACSystems RX3i platform, developed for precise pulse acquisition and motion-related measurements. Unlike standard I/O modules, it processes high-frequency signals locally, eliminating dependence on PLC scan time and ensuring accurate real-time performance.

With support for multiple counting modes and high-frequency inputs, the module is suitable for encoder feedback, flow measurement, and fast event tracking. Integrated outputs and interrupt capabilities allow it to directly control field devices based on counting conditions.
