Advantages & Features

1. SIL 3 Certification for Maximum Safety: HONEYWELL FC-DO-1624 is certified to IEC 61508 SIL 3, making it suitable for the most critical safety applications (e.g., emergency shutdown systems, fire/gas protection) where failure could result in catastrophic consequences.
2. High-Density Isolated Outputs: With 16 isolated channels in a compact module, HONEYWELL FC-DO-1624 reduces hardware count and cabinet space requirements, while channel isolation prevents cross-talk and fault propagation between outputs.
3. Fail-Safe Design & Advanced Diagnostics: The module supports configurable fail-safe states (e.g., valve close on power loss) and provides real-time alerts for short circuits, overcurrent, and transistor faults—enabling proactive maintenance and preventing unsafe operating conditions.
4. Redundancy Support: HONEYWELL FC-DO-1624 integrates with Honeywell’s redundant SIS architectures, supporting dual-module and dual-channel configurations to eliminate single points of failure in safety-critical systems.

Application Fields & Cases

1. Oil Refinery Emergency Shutdown System (ESD): A major oil refinery deployed HONEYWELL FC-DO-1624 modules in its Safety Manager ESD system to control emergency shutdown valves (ESVs) and pump trip circuits in a crude oil processing unit. The SIL 3 certification ensured compliance with API 556 standards, while diagnostic capabilities detected a short circuit in an ESV signal line before it caused a safety incident.
2. Chemical Plant Reactor Safety System: A petrochemical plant integrated HONEYWELL FC-DO-1624 into its FSC system to control emergency isolation valves and pressure relief systems for polymerization reactors. The module’s fail-safe design ensured valves closed automatically during power loss, preventing reactor overpressure and potential explosions.
3. Power Plant Fire & Gas Protection System: A combined-cycle power plant used HONEYWELL FC-DO-1624 to trigger fire suppression systems and gas detection alarms in its turbine hall. The module’s fast response time (<1ms) ensured immediate activation of safety systems, while Zone 2 certification allowed installation in hazardous gas environments.

Competitor Comparison

Selection Suggestions & Precautions

1. Selection Suggestions: HONEYWELL FC-DO-1624 is ideal for Honeywell Safety Manager/FSC users requiring SIL 3-certified digital outputs for critical SIS applications (e.g., ESD, fire/gas systems). For Siemens S7 F-system users, Siemens FDO 8DO Module is preferred; Allen-Bradley 1756-OB16D suits GuardLogix systems (note: SIL 2 only).
2. Precautions:
   • Configure fail-safe states (on/off) per channel via Safety Builder/FSC Configurator to align with safety requirements (e.g., ESV close on module fault).
   • Use shielded twisted-pair cables for output wiring to minimize EMI interference, especially in high-noise industrial environments (e.g., near motors or switchgear).
   • Do not exceed the module’s continuous output current rating (0.5A per channel) to prevent transistor damage and ensure long-term reliability.
   • Verify redundant power supply connections (24V DC from two independent sources) to maintain fail-safe operation during power supply failures.
   • Ensure ATEX/IECEx certification matches the hazardous zone classification (Zone 2 only; not suitable for Zone 1 areas without additional protection).
