3. Product Specifications & Features
3.1 Core Specifications
The ABB PFSK163 3BSE016323R3 is optimized for safety-critical control, with dual-core redundancy ensuring no single-point failure—critical for SIL 3 applications (e.g., refinery emergency shutdown systems). Its ability to connect 32 safety I/O modules supports large-scale SIS (e.g., monitoring 100+ safety sensors across a chemical plant), while non-volatile memory logs up to 1000 fault events for post-incident analysis.
Dual Ethernet ports enable separate safety and non-safety communication (e.g., Profinet for safety I/O, Modbus TCP/IP for HMI monitoring), preventing cross-interference. The 24 V DC redundant power input further enhances reliability, ensuring continuous operation even if one power source fails.
3.2 Key Features
- SIL 3 Compliance: Meets the highest safety standards for high-risk industries, ensuring safety functions are executed reliably.
- Dual-Core Redundancy: Eliminates single-point failures, minimizing unplanned downtime in safety-critical systems.
- Scalable I/O Expansion: Supports up to 32 safety I/O modules, adapting to small-to-large SIS configurations.
- Dedicated Safety Bus: SafeBus ensures secure, real-time communication with safety I/O, avoiding data corruption.
- Intuitive Programming: ABB SafePLC Configurator simplifies safety logic development, with built-in tools for SIL verification.
