General Electric Fanuc IC695HSC304-DA High-speed Counter Module

The GE Fanuc IC695HSC304-DA is a powerful High-Speed Counter (HSC) Module designed for use with the PACSystems RX3i automation platform. This advanced module provides independent, high-speed counting capabilities for up to 4 input channels, enabling precise measurement and control of pulse-based signals from encoders, proximity sensors, flowmeters, and other frequency-based input devices.

Unlike standard input modules that depend on CPU scan times, the HSC304-DA processes signals asynchronously, allowing accurate counting even at very high frequencies. It is an essential component in applications that require real-time position tracking, speed monitoring, or event timing.

Key Features

• 4 independent high-speed counting channels

• Supports up to 1 MHz input frequency per channel

• Configurable for multiple modes: quadrature, up/down, pulse/direction, frequency measurement

• Four 24VDC sink or source inputs per channel

• Dedicated onboard processor for real-time counting independent of CPU

• Latch, preset, and compare functions per channel

• Supports interrupts to CPU based on event triggers

• DIN-rail mountable in RX3i rack

• Hot-swap capable

• LED indicators for power and per-channel status

• Compatible with Proficy Machine Edition for configuration and diagnostics
