SM812K01 3BSE072270R1 SAFE CPU MODULE

Product Identification

• Model Number: SM812K01

• Product ID / Part Number: 3BSE072270R1

• Product Type: Safety CPU Module Kit / High Integrity Controller Module

• Product Family: System 800xA / AC 800M Control IT Series

Technical Specifications

• Safety Certification: Certified for use in safety-critical applications up to SIL 3 (Safety Integrity Level 3) according to IEC 61508, and Category 4 / PLe according to ISO 13849-1.

• Architecture & Redundancy: Functions as the dedicated safety co-processor or High Integrity controller unit. It features an internal diverse 1oo2D (1-out-of-2 with diagnostics) hardware architecture to ensure that internal component failures are immediately detected and handled safely.

• Memory & Performance: Optimized for high-speed execution of safety-related application logic, interlocking configurations, and cause-and-effect matrices with strict deterministic cycle times.

• Integration Capacity: Interconnects seamlessly with standard PM865 or PM867 processor modules to provide an integrated but physically distinct control environment where standard process logic cannot interfere with safety functions (Interference-Free execution).

• Communication: Utilizes secure, safety-certified protocols (such as Safe Peer-to-Peer over Ethernet) to communicate safely with other High Integrity controllers and safety I/O modules (e.g., S800 I/O High Integrity).

Target Industries

The SM812K01 kit is deployed in high-risk sectors where a system failure could result in environmental disasters, severe asset destruction, or loss of human life:

• Oil & Gas (Upstream & Downstream): Offshore production platforms, LNG terminals, pipelines, and oil refineries.

• Petrochemicals & Chemicals: Ethylene plants, hazardous chemical storage facilities, and complex polymer processing lines.

• Power Generation: Conventional thermal, combined-cycle, and nuclear power utilities requiring Emergency Shutdown (ESD) mechanisms.

• Mining & Materials: High-tonnage underground mining hoists, hazardous material handling systems, and smelters.

Applications and Use Cases

• Emergency Shutdown Systems (ESD): Acts as the master safety brain that instantly isolates processes, closes emergency valves, and depressurizes pipelines when critical process boundaries are crossed.

• Burner Management Systems (BMS): Controls the safe ignition, monitoring, and shutdown of large industrial boilers, furnaces, and kilns, preventing explosive fuel accumulation.

• Fire & Gas Systems (F&G): Aggregates telemetry from flame, smoke, and toxic gas detectors, initiating automated mitigation sequences (like deluge systems) while maintaining SIL 3 availability.

• High-Pressure Protection Systems (HIPPS): Deployed as a high-speed safety mechanism to isolate upstream high-pressure sources before down-stream low-pressure piping design limits are breached, replacing conventional mechanical relief valves.
