Features:

  • Multi-Channel Advanced Pulse Signal Conversion
  • Onboard Dual Fault and Supervision Hardware Relays
  • Dedicated Configuration and EEPROM Non-Volatile Memory
The ABB HESG447398R20 HE666710-318/1 70EA06a-E effectively converts raw pulse signals from proximity probes into two frequency-proportional signals. This enables real-time local bus tracking of both full-scale velocities and zoomed operational speed ranges simultaneously.

Equipped with two integrated safety-rated relays, the ABB HESG447398R20 HE666710-318/1 70EA06a-E offers 3 NO and 1 NC potential-free contacts. These local physical contacts allow engineers to hardwire trip outputs directly into standalone ESD or 2oo3 voting architectures.

The ABB HESG447398R20 HE666710-318/1 70EA06a-E board contains an internal EEPROM chip and a dedicated front panel programming connector. This architecture ensures that user-defined speed thresholds, hysteresis loops, and fault-conditioning variables are retained permanently even during complete system power losses.

The HESG447398R20 HE666710-318/1 70EA06a-E ABB Procontrol P13 Rotational Speed Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Thermal & Hydro Power Plant Turbines: Deployed to constantly calculate rotational velocities of steam or hydro turbines, protecting multi-million-dollar generators from centrifugal destruction caused by overspeeding.
  • Large Turbo-Compressors in Petrochemical Plants: Used to manage and monitor massive compressors within gas pipelines and petrochemical processing plants, where precise speed control is essential for preventing dangerous system surges.
  • Heavy Industrial Metal & Rolling Mills: Utilized in automated facilities requiring precise synchronization of massive motor shafts, ensuring continuous process uptime and immediate safety trip capability.
  • Marine Propulsion Control Infrastructure: Embedded within automated systems for large transport vessels to track shaft speeds, providing direct hardware-level diagnostics and fault prevention tools for critical marine engines.
  • Dual-Range Analog Scaling Over Local Bus: The module processes raw frequency signals and breaks them down into two specialized local bus outputs: a full operational range and a zoomed range. This significantly enhances accuracy during critical start-up or trip testing phases.
  • Hardware-Driven Real-Time Algorithms: Integrated algorithms execute continuous, latency-free onboard computations. This allows instant tracking of turbine acceleration rates, overspeed thresholds, and sudden loss-of-signal events.
  • Direct 2oo3 Trip Voting Execution: With two dedicated safety relays onboard, multiple cards can be networked into hardware configurations. This setup permits direct, un-delayed physical execution of protective trips without waiting for central processor logic loops.
  • Permanent Configurations via Local EEPROM: All customized speed settings and trip parameters are written directly onto an onboard EEPROM via the front panel serial port. This ensures instant plug-and-play boot-up efficiency without losing vital calibrations during maintenance outages.
  • Designed for IEC 61508 Safety Compliance: The underlying engineering architecture of this series aligns with functional safety design philosophies. Its direct evolutionary successor, the 70E106a, formally achieves SIL3 rating compliance.
  • Potential-Free Isolation Standards: The potential-free layout of the onboard relay change-over contacts ensures high galvanic isolation. This safeguards sensitive bus electronics from extreme field-side electrical surges.
  • Standardized Eurocard 1T Form Factor: Designed according to the standard Procontrol P13 mechanical format (1T wide card slot). This configuration simplifies cabinet cooling dynamics and standardizes rack grounding pathways.
  • Strict Process Supervision Controls: Adheres to industrial alarm classification guidelines by separating critical board hardware faults from general process supervision field alarms.
