- Input Response Time: ≤ 3ms (ON/OFF switching).
- Output Contact Life: 100,000 operations (resistive load).
- Isolation Voltage: 1500V AC (between channels / channel to ground).
- Operating Temperature: -40°C ~ +85°C.
- Protection Class: IP52 (front panel).
- Backplane Communication: Dual redundant VME bus.
- MTBF: 300,000 hours (IEC 61709).
Product Features
- High Reliability: Certified by SIL2/API 670, with short-circuit self-cutoff function to prevent misoperation.
- Anti-Interference Capability: 1500V AC isolation between channels and TVS diode protection to resist electromagnetic noise.
- Anti-Vibration Performance: Passed IEEE 344 Class 1 test, capable of withstanding 15G continuous shock.
- Self-Diagnostic Status: Real-time monitoring of faults such as relay contact adhesion and coil open circuit, with pre-maintenance alarms triggered via ToolboxST software.
- Dual Redundant Architecture: Supports parallel operation with DS3800HRMD1C2B module, enabling automatic switching in case of faults, with system availability > 99.99%.
Structure and Composition
- All-Metal Shielding Enclosure: Provides excellent electromagnetic shielding and protection.
- Three-Layer Internal Structure:
- Signal Acquisition Layer: Input channels are equipped with photoelectric isolation and Schmitt triggers to eliminate contact bounce, supporting 15-30V DC wide-voltage input.
- Output Drive Layer: Adopts latching relays, with built-in arc suppression circuits and contact wear monitoring; output status is indicated in real time via red LEDs.
- Communication and Power Layer: Dual redundant DC/DC power modules (24V DC input) supporting millisecond-level fault switching, and exchanging data with Mark IV controller via gold-plated backplane connectors.
Application Fields
- Power Industry: Power generation, transmission and distribution, power grid control and protection, including thermal power plants, hydropower plants, wind farms, etc.
- Oil and Gas Industry: Automation control and monitoring for extraction, processing, and transportation processes.
- Chemical Industry: Automation control, instrument monitoring, and safety systems.
- Manufacturing Industry: Control and monitoring of mechanical equipment to improve production efficiency and quality.
- Transportation Industry: Traffic signal control systems, railway signal systems, ship automation control, and other fields.
Installation and Maintenance
- Installation: The module can be directly installed in switchgear, meeting UL standards to enhance installation flexibility.
- Maintenance: Equipped with self-diagnostic status function for real-time fault monitoring; pre-maintenance alarms are provided via ToolboxST software to reduce downtime.
- Warranty: Offers a 7-day acceptance period and a 1-year warranty period.
