TRICONEX 3664 24VDC DUAL DO Digital Output Module – Functions & Features
1. Primary Functions
Dual-Channel 24VDC Digital Output:
Provides two independent 24VDC output channels for controlling actuators, relays, and solenoid valves in safety-critical systems.
Designed for high-integrity applications such as Emergency Shutdown (ESD) and Fire & Gas (F&G) systems.
Triple Modular Redundancy (TMR) Support:
Works within Triconex TMR architecture to ensure fault tolerance and SIL3 compliance (IEC 61508).
2. Key Features
Supervised Output Monitoring:
Continuously checks for open circuits, short circuits, and load failures, providing diagnostic feedback to the control system.
Hot-Swappable Design:
Allows online replacement without interrupting system operations.
LED Status Indicators:
Per-channel LEDs display output state (ON/OFF) and fault conditions for quick troubleshooting.
3. Typical Applications
Emergency Shutdown (ESD) Systems:
Controls critical shutdown valves, pumps, or motors in oil & gas, chemical, and power plants.
Process Automation:
Manages safety interlocks, alarms, and motor control circuits in industrial environments.
Power Distribution Protection:
Triggers circuit breakers or isolation switches in electrical substations.
4. Advantages
High Reliability: Certified for SIL3 safety standards, ensuring fail-safe operation.
Seamless Integration: Compatible with other Triconex modules (e.g., 3504E, 3604E) for scalable safety solutions.
