IC697HSC700 GE Fanuc Series 90-70 High-Speed Counter Module

Product Overview

The GE Fanuc IC697HSC700 is a high-performance, single-slot High-Speed Counter (HSC) module designed for the Series 90-70 PLC system. Engineered for real-time motion control, turbine pulse monitoring, and high-speed material handling, it processes input pulse frequencies up to 200 kHz (or up to 800 kHz in Type E Quadrature x4 mode). Featuring 4 integrated positive logic outputs with short-circuit protection, the IC697HSC700 provides rapid direct output response independent of PLC scan times. Weighing approximately 0.22 kg (0.49 lbs), it offers high-density counting performance in a lightweight module footprint.

Technical Specifications

Key Design & Hardware Features

• High-Speed Pulse Input Processing: Accurately tracks high-speed encoder feedback up to 200 kHz for precise position, velocity, and length measurement.
• Direct Onboard Outputs: Includes 4 fast-responding outputs that trigger based on pre-set counter match values, bypassing PLC CPU scan delay.
• Flexible Signal Modes: Configurable for multiple counting modes, including Up/Down counting, Pulse/Direction, and Quadrature A/B encoder inputs.
• Built-In Circuit Diagnostics: Integrated short-circuit protection and front-panel status LEDs enable visual diagnostic feedback during commissioning.

Installation & Engineering Guidelines

1. Encoder Signal Selection: Select the correct input jumpers or field wiring connections depending on whether your rotary encoder provides 5 VDC differential signals or 10–30 VDC single-ended signals.

2. Shielding & Cable Grounding: Always use twisted-pair shielded cables for high-speed input signals and ground the shield at the module terminal block to suppress high-frequency electrical noise.

3. External Field Power: Connect an external 10–30 VDC power supply to the module terminal block to energize the onboard positive logic output channels.

Frequently Asked Questions (FAQs)

Q1: Can the IC693 series PLCs use the IC697HSC700 module?
A1: No. The IC697HSC700 is specifically designed for the GE Fanuc Series 90-70 backplane and is not physically or electrically compatible with Series 90-30 racks.

Q2: What is the maximum counting frequency supported by the IC697HSC700?
A2: The module supports standard input pulse rates up to 200 kHz, which translates to an effective 800 kHz count rate when configured in Quadrature x4 mode.

Q3: How do the onboard outputs operate relative to the PLC scan cycle?
A3: The 4 onboard outputs operate asynchronously to the CPU scan. They trigger instantly when internal counter registers reach target setpoints, providing millisecond-level response times.
