Description
3625 Invensys | Triconex | in stock
The 3625 is a high-performance, fault-tolerant programmable logic controller (PLC) module manufactured by Triconex, specifically designed for critical control and safety applications in industries such as petrochemicals, power generation, and metallurgy.
I. Core Functions
- High-Performance Processing:
- Equipped with a 32-bit processor (33MHz clock speed), 1MB RAM, and 4MB flash memory, enabling efficient logic operations and storage of complex control logic.
- Triple Modular Redundancy (TMR) Architecture:
- Features three independent processors executing identical logic simultaneously. A single-point failure does not affect overall operation, achieving system availability of up to 99.999%.
- Multi-Protocol Communication:
- Supports industrial protocols such as Modbus, DNP3, and OPC, with compatibility for Ethernet, serial ports, and CAN bus interfaces, facilitating high-speed data exchange with diverse devices.
- Real-Time Monitoring and Alarming:
- Built-in fault detection mechanisms continuously monitor communication status. Abnormalities trigger automatic alarms and record Sequence of Events (SOE) with a resolution of ≤40 milliseconds.

II. Technical Specifications
- I/O Capacity:
- Supports up to 1,000 analog input/output points and 2,000 digital input/output points, meeting large-scale equipment control requirements.
- Environmental Adaptability:
- Operates in temperatures ranging from -40°C to 70°C, with an IP67 protection rating for dustproof, waterproof, and vibration-resistant performance in harsh industrial environments.
- Power Configuration:
- Accepts 90–264VAC power input with redundant power supply design for automatic switching, ensuring stable operation.
- Scalability:
- Modular design allows expansion of I/O modules as needed to accommodate systems of varying scales.
III. Application Scenarios
- Petrochemical Industry:
- Controls reactor temperature and pressure, implements emergency shutdown (ESD) and safety interlocks to safeguard production.
- Power Generation:
- Monitors generator unit operation, optimizes grid stability, and prevents outages caused by equipment failures.
- Metallurgy and Paper Manufacturing:
- Optimizes production line timing control to enhance efficiency and reduce equipment wear.
- Safety Systems:
- Integrated into burner management systems (BMS) and fire detection systems to ensure personnel and equipment safety.
IV. Key Advantages
- High Reliability:
- TMR architecture and self-diagnostic functions (executed every 60 seconds) ensure stable operation, with fault switching time ≤5 seconds.
- Safety Certification:
- Certified to SIL2 under IEC 61508 standards, suitable for safety-critical applications.
- Programming Flexibility:
- Supports IEC 61131-3 standard programming languages (e.g., ladder logic, function block diagrams), simplifying logic development.
- Remote Management:
- Ethernet interface enables remote monitoring, configuration, and firmware updates, reducing maintenance costs.
The 3625 Triconex stands out for its robustness, safety compliance, and versatility, making it a trusted choice for mission-critical industrial automation.
