Description

Functional Features

  • Triple Modular Redundancy (TMR): Each input signal is processed by three independent channels, ensuring fault tolerance through a 2-out-of-3 voting mechanism. This eliminates single points of failure and guarantees continuous operation even if one or two channels fail.
  • High-Precision Data Acquisition: Supports pulse width resolution down to 100 μs and frequency ranges up to 10 kHz, enabling accurate monitoring of rotational speeds and vibrations.
  • Comprehensive Diagnostics: Each channel features continuous self-diagnostics to detect faults (e.g., stuck-on/stuck-off conditions, wire breakage, short circuits). Any failure activates a fault indicator and triggers system alarms.
  • Flexible Signal Processing: Offers low-pass, high-pass, and band-pass filters to suppress noise and ensure signal integrity in electrically noisy environments.
  • High Reliability: Built with industrial-grade components to withstand extreme temperatures, vibrations, and electromagnetic interference (EMI).
  • Hot Swapping: Modules can be replaced without powering down the system, minimizing downtime and maintenance costs.
  • Scalability: Supports up to 118 I/O modules (including analog and digital) and optional communication modules for large-scale deployments.
  • Programmable Logic Control: Allows users to write and execute custom control logic tailored to specific application requirements.

Application Scenarios

  • Oil and Gas Industry: Emergency shutdown systems (ESD), fire and gas detection (F&G), and wellhead pressure monitoring.
  • Petrochemical Plants: Safety instrumented systems (SIS) for monitoring reactors, distillation columns, and storage tanks.
  • Power Generation: Turbine control, generator monitoring, and auxiliary system protection in thermal and nuclear power plants.
  • Mining and Metallurgy: Conveyor control, ventilation systems, and gas detection in underground mines.
  • Manufacturing: Precision control and monitoring of rotating equipment (e.g., motors, pumps, fans).
  • Transportation: Vehicle control systems for rail and marine applications.
  • Water Treatment: Pump and valve control in municipal and industrial water treatment facilities.

Advantages

  • Unmatched Reliability: TMR architecture ensures continuous operation even under fault conditions, providing the highest system availability.
  • High Precision: Sub-millisecond signal processing enables timely detection of input changes, critical for safety-critical applications.
  • Cost Efficiency: Reduces long-term maintenance costs through modular design, online diagnostics, and hot-swappable capabilities.
  • Versatility: Integrates seamlessly with various industrial equipment and systems via multiple communication protocols.
  • Robustness: Withstands extreme temperatures, humidity, and vibrations, ensuring reliable performance in harsh industrial environments.
  • Scalability: Easily expands to accommodate increasing control demands without system overhaul, making it suitable for evolving industrial needs.
