Product Overview

Core Functions

1. High-Performance Real-Time Control Processing: Equipped with an embedded processor, running QNX real-time operating system, performing millisecond-level closed-loop control, logic operation, PID regulation and redundant voting, meeting high real-time and deterministic requirements of TMR systems.

2. High-Speed VME Bus Communication: Compatible with VME64 standard bus, high-speed data interaction with system backplane, I/O modules and other controllers, supporting multi-module collaboration and redundant synchronization.

3. Multi-Protocol Redundant Communication: Integrates dual Ethernet (E-Net/IONet), 2 ISBUS channels and 1 Genius bus, realizing redundant communication between controllers, controller-to-I/O and host/remote systems, ensuring uninterrupted data transmission.

4. Redundancy & Fault Tolerance: Supports TMR triple redundancy/dual redundancy configuration, hardware voting, fault isolation and bumpless switching; single controller failure does not affect unit safe operation, complying with SIL safety level requirements.

5. Local Storage & Diagnostics: On-board Flash/DRAM for storing control programs, parameters and historical data; built-in hardware self-test, channel diagnostics and status LEDs for real-time module health monitoring and fast fault location.

6. Industrial-Grade Stable Design: Wide temperature range, anti-vibration, anti-EMI, UL94 V‑0 flame retardant, adapting to harsh industrial environments in power plants, supporting hot-swappable maintenance.
