TRICONEX 3624 Digital Output Module (24VDC) – Key Functions & Features
1. Primary Functions
Safety-Critical Digital Output Control:
Provides 24VDC digital outputs to drive relays, solenoid valves, and other field devices in high-reliability industrial applications (e.g., Emergency Shutdown Systems, Fire & Gas protection).
Executes real-time control commands from Triconex Safety Instrumented Systems (SIS) to ensure fail-safe operations.
Triple Modular Redundancy (TMR):
Employs three independent output channels with voting logic to achieve fault tolerance, meeting SIL3 safety standards.
2. Key Features
Supervised Output Monitoring:
Detects faults like open circuits, short circuits, or load failures, triggering alarms for immediate maintenance.
Hot-Swappable Design:
Supports online replacement without system downtime, enhancing operational continuity.
Diagnostic Indicators:
LED status lights per channel (active/fault) enable rapid troubleshooting.
3. Typical Applications
Emergency Shutdown (ESD) Systems:
Controls critical actuators (e.g., shutdown valves) in oil/gas or chemical plants.
Process Automation:
Manages motor start/stop, alarm triggers, and other logic operations in production lines.
Power Grid Protection:
Operates circuit breakers or isolators in electrical substations.
4. Advantages
High Reliability: Certified for IEC 61508 and SIL3 compliance.
Seamless Integration: Compatible with other Triconex modules (e.g., 3504E, 3604E) for scalable safety systems.
