The HIMA F8627X is a high-integrity safety-certified controller engineered for the most demanding safety instrumented systems (SIS) in hazardous industrial environments. As a flagship product of HIMA Paul Hildebrandt GmbH, this modular safety PLC achieves SIL 4 (IEC 61508/61511) and AK7 (DIN V 19250) certifications for applications requiring ultra-reliable emergency shutdown (ESD), fire and gas protection (F&G), and critical process control. Featuring quad-redundant “2oo4” voting architecture, the HIMA F8627X delivers deterministic sub-50ms reaction times while supporting up to 8,000 I/O points across distributed networks. Its ruggedized design operates flawlessly from -40°C to +70°C, making it ideal for Arctic drilling platforms, chemical processing plants, and high-speed rail safety systems where functional safety cannot be compromised.
The controller leverages hardware-based fault detection and TÜV-certified firmware to maintain <10>HIMA F8627X executes safety logic in dedicated FPGAs, eliminating operating system vulnerabilities. Integrated cybersecurity features meet IEC 62443 standards, providing robust protection against unauthorized access in connected industrial ecosystems.

Main Features and Advantages
Uncompromised safety integrity: Quad-CPU architecture with continuous cross-comparison achieves hardware fault tolerance (HFT=3). The HIMA F8627X provides automatic channel synchronization and <1ms>
Deterministic performance: Hardware-triggered safety interrupts bypass standard processing cycles, guaranteeing sub-50ms response even during CPU overload. Integrated watchdog timers validate execution every 5ms.
Future-proof connectivity: Native support for Ethernet-APL (100 Mbit/s) enables long-distance intrinsic safety (IS) field device integration. OPC UA Pub/Sub simplifies IT/OT convergence without protocol gateways.
Advanced cyber protection: Secure boot with cryptographic signature verification and role-based access control (RBAC) meets NAMUR NE153 recommendations. Unauthorized configuration changes trigger immediate safety state transition.
Application Field
The HIMA F8627X secures mission-critical processes:
Oil & Gas: SIL 4 emergency shutdown for LNG terminals handling -162°C cryogenic fluids
