Core Product Functions

1. Execute safety control logic for Emergency Shutdown (ESD) system to cut off equipment under dangerous conditions

2.Collect fire, gas leakage, pressure over-limit, temperature abnormal field safety detection signals

3. Issue tripping, valve cut-off, fan stop and audible alarm safety output commands

4.Realize bidirectional data communication between Honeywell SIS safety system and conventional DCS BPCS system

5.Store safety configuration programs, fault event logs and abnormal action records for trace analysis

6. Support redundant network communication to ensure continuous safety system operation

7.Match SC S300 full series I/O modules to build complete distributed safety monitoring & interlock system

Product Advantages

1. SIL3 highest safety integrity level, zero single-point failure risk for critical process safety

2. Perfect compatibility with Honeywell Safety Manager, Experion PKS DCS platform, no extra conversion equipment

3. Redundant architecture greatly improves system availability, avoids safety function loss caused by single module fault

4. Integrated multi-protocol communication reduces intermediate gateway modules and cabinet wiring cost

5.Ruggedized structure adapts to high-dust, high-humidity, flammable industrial harsh environment

6. Hot-swap maintenance minimizes production halt time for industrial plant overhaul

7.Mature stable spare part for old Honeywell SIS safety system upgrade, renovation and replacement

Typical Application Cases

1.Petrochemical Refinery: ESD emergency shutdown control for cracking unit, reactor and pressure vessel safety interlock

2.Onshore & Offshore Oil & Gas Field: Fire & gas leakage monitoring and platform equipment safety protection control

3.Thermal Power Plant: Boiler furnace safety interlock, turbine overspeed protection and fuel cut-off control

4.Chemical Fertilizer Plant: High-pressure reaction workshop hazardous condition monitoring and emergency tripping

5.LNG Terminal: Storage tank leakage detection, pipeline pressure protection and whole-site safety linkage control

6.Coal Chemical Industry: High-risk workshop gas monitoring, anti-explosion interlock and safety alarm system control

Product Characteristics

1. Dual-core redundant processor design with millisecond-level master-slave seamless switching

2. Complete channel galvanic isolation to eliminate ground loop interference and signal crosstalk

3. SIL3 certification complying with IEC61508 / IEC61511 industrial functional safety standard

4. Wide operating temperature: -40°C ~ +70°C; storage temperature: -40°C ~ +85°C

5.Full hardware self-diagnosis: power monitoring, channel fault detection, abnormal alarm recording

6. Front LED indicators for power, running status, communication and each channel working state

7.High-level EMC anti-electromagnetic interference, anti-vibration for explosive industrial environment

8. Standard rack modular installation, support hot-plug maintenance without system shutdown

9. Passed CE, UL, FM Class I Div 2 hazardous area certification
