Functional Features:
- TMR triple‑channel parallel computation and hardware majority voting, eliminate single‑point failure risk
- Higher logic scanning speed for large‑scale complex safety interlock programs
- High‑precision sequence‑of‑events recording for post‑accident analysis
- Full hot‑swap capability, online replacement without halting safety function
- Comprehensive continuous diagnostics covering processor, memory, bus and power circuits
- Multiple front‑panel LED indicators for running, standby, fault and communication status
- Support IEC 61131‑3 programming suite, including ladder diagram, function block, structured text
- Fault relay dry‑contact output for external alarm system connection
- Support redundant communication link to expander I/O racks
Working Principle: Three independent processing channels receive identical input data from I/O modules, execute safety logic simultaneously. Hardware voting circuit compares output results of three channels. Abnormal channel will be diagnosed and isolated automatically without disturbing overall system output. All fault events obtain millisecond‑level time stamp and stored in non‑volatile memory. Processed valid control data is transmitted to local and remote expander racks through inter‑module bus.
Material Composition & Structural Characteristics:
- Housing: Die‑cast aluminum alloy shell with anti‑corrosive coating
- Circuit substrate: High‑reliability multi‑layer FR‑4 industrial PCB
- Connector: Gold‑plated high‑density backplane connector, anti‑vibration and anti‑oxidation
- Front panel: Flame‑retardant PC engineering plastic, equipped with status LED array and diagnostic serial port
- Card‑type insert structure, IP20 protection grade, suitable for indoor control cabinet installation
Installation Requirements:
- Insert to primary CPU slot of Trusted main rack, fasten front‑panel locking screws
- Main rack must adopt dual redundant 24 V DC power supply
- Control cabinet provides sufficient air circulation, ambient temperature shall not exceed 70 °C
- Cabinet protective ground connection is mandatory, ground resistance ≤4 Ω
- All communication wiring uses shielded industrial cable, shielding layer grounded at cabinet ground bar
- Keep proper spacing between modules for heat dissipation
Application Scenarios:
- Large‑scale petrochemical ESD emergency shutdown systems
- Offshore platform integrated fire‑gas and process safety interlock
- Power plant boiler and turbine safety protection system
- LNG receiving station and storage tank safety instrumented system
- Hazardous chemical production safety interlock with large I/O point count
Usage Notes:
- Hot‑swap operation is only allowed when the system reports normal health status
- Do not disassemble module shell; internal components cannot be maintained on site
- Prevent violent impact and excessive vibration during handling and installation
- Prohibit operation beyond the rated temperature range
- After replacement, complete offline configuration download and full function test before online commissioning
- Avoid long‑term total power‑off to prevent loss of NVRAM stored event records
