QMR (Quadruple Modular Redundant) |
The F8641 is a high-performance CPU module from HIMA, engineered as the core processing unit for H41q and H51q series safety controllers. This F8641 module features a 32-bit processor with 200 MHz speed and 128 KB RAM, delivering robust real-time control for critical applications. The F8641 incorporates QMR (Quadruple Modular Redundant) architecture, ensuring fault tolerance and continuous operation. As a TÜV-certified SIL 3 device, the F8641 is purpose-built for emergency shutdown systems (ESD), fire and gas detection, and other safety-instrumented functions.
TÜV-Certified SIL 3 Compliance – Meets IEC 61508, IEC 61511, and EN 954-1 Cat. 4 / PL e standards, eliminating the need for separate certification efforts
QMR Redundant Architecture – Quadruple modular redundancy ensures system operation continues even during hardware failures
Seamless System Integration – Compatible with HIMA H41q/H51q controllers, DCS, and PLC systems
Harsh Environment Ready – Wide operating temperature range (-20°C to +70°C) and robust construction suit demanding industrial conditions
Built-In Cybersecurity – High degree of IT security by design, integral to safety system protection
32-Bit Microprocessor – High-speed computation for real-time safety control and rapid data processing
QMR (Quadruple Modular Redundant) Architecture – Four microprocessors integrated on the CPU module for maximum fault tolerance
Dual Memory Configuration – 128 KB RAM for runtime data + 1 MB flash memory for program storage
Built-In Self-Diagnostics – Continuous fault monitoring and alarm system for rapid issue identification
Multi-Tasking Support – Independent task processing with user-definable cycle times per task
Flexible Mounting Options – Supports both panel mount and rack mount installations
Advanced Communication – RS-485 and Modbus protocols for seamless industrial connectivity
The F8641 is engineered for reliable operation in harsh industrial environments, with an operating temperature range of -20°C to +70°C and humidity tolerance of 5% to 95% non-condensing. The module carries TÜV certification for safety integrity level SIL 3 per IEC 61508, IEC 61511, and IEC 62061 standards. Additional certifications include CE Mark, UL listing, and ATEX compliance for hazardous area installations. The F8641 satisfies AK6/SIL3 safety requirements and incorporates IT security by design at all system levels. The module is manufactured in Germany to HIMA's rigorous quality standards.
Q1: What is the HIMA F8641 used for?
The F8641 is a CPU module serving as the central processing unit for HIMA H41q and H51q safety instrumented systems (SIS), used in emergency shutdown (ESD), fire and gas detection, burner management, and other safety-critical control applications.
Q2: What safety certifications does the F8641 hold?
The F8641 is TÜV-certified for SIL 3 per IEC 61508, IEC 61511, and IEC 62061. It also carries CE, UL, and ATEX certifications for hazardous area deployment.
Q3: What is QMR architecture in the F8641?
QMR (Quadruple Modular Redundant) means the F8641 integrates four microprocessors. This redundant design ensures the system continues safe operation even if one or more processor components fail.
Q4: What communication protocols does the F8641 support?
The F8641 supports RS-485 and Modbus communication protocols. Some configurations also support Profibus, Profinet, and Hart protocols for flexible integration with existing automation systems.
Q5: Is the F8641 still in production?
The F8641 has been officially discontinued by HIMA and is no longer actively supported. However, new original modules remain available through authorized distributors and spare parts suppliers with warranty coverage.
