PACSystems RX3i IC695HSC308 High-Speed Counter Module

Product Overview

The GE PACSystems RX3i IC695HSC308 serves as a high-performance, multi-channel High-Speed Counter (HSC) module designed for the most demanding motion control and position-tracking applications. This module executes high-velocity pulse processing independently of the PLC scan time, allowing it to capture events up to 1 MHz. With eight independent 32-bit counter channels, it interfaces directly with quadrature encoders, flow meters, and proximity sensors. Engineers deploy the IC695HSC308 in complex machine automation and energy systems where real-time speed monitoring and sub-millisecond event synchronization remain critical to operational success.

Technical Specifications

Engineering Advantages

The IC695HSC308 provides technical solutions for high-precision motion and flow applications:

• Superior High-Frequency Capture: The 1 MHz input capability allows the module to track ultra-high-speed machinery and high-resolution encoders without dropping pulses. This ensures absolute position accuracy during rapid acceleration and deceleration phases in motion control loops.

• Deterministic Real-Time Processing: By offloading pulse counting to the dedicated 32-bit onboard hardware, the module ensures that high-speed inputs never impact the PLC CPU scan rate. This hardware-based counting provides deterministic performance, even when all eight channels operate simultaneously at maximum frequency.

• Versatile Signal Compatibility: The module supports both 5 VDC TTL and 24 VDC signal levels. This flexibility allows technicians to integrate a wide variety of field devices, from delicate lab-grade encoders to rugged industrial flow sensors, without requiring external signal conditioners.

• Advanced Electrical Isolation: Integrated channel-to-backplane isolation protects the RX3i system logic from field-side electrical noise and transient voltage spikes. This robustness prevents data corruption in harsh environments near high-power variable frequency drives (VFDs).

FAQs

• Is this GE IC695HSC308 unit 100% Brand New?

  Yes. We supply the IC695HSC308 in 100% Brand New and Original condition. Each module arrives in factory-sealed industrial packaging to guarantee hardware integrity and a full operational lifespan in your RX3i system.

• Can the IC695HSC308 measure frequency and velocity?

  Yes. In addition to standard pulse counting, you can configure the channels for frequency measurement and time-interval measurement. This makes the module ideal for monitoring turbine speeds or calculating flow rates in process control applications.

• Does this module support A/B phase quadrature encoders?

  Absolutely. The IC695HSC308 supports full quadrature encoder inputs (A, B, and Z/Index signals). The 32-bit resolution ensures the module can track extremely long travel distances without counter overflow.

• How do I configure the input voltage levels?

  Voltage level selection occurs via hardware wiring and software configuration within the PACSystems RX3i programming environment. Ensure you match the field device output (5V or 24V) to the module settings to prevent damage and ensure accurate signal detection.
