HIMA F8650X
Safety-System CPU Module
Technical Specification & Application Guide
(PLC Autocontroller – 20 Years Certified Supply)
Executive Summary
The HIMA F8650X is the central, SIL-3-rated CPU for HIMA HIMatrix and HIQUAD safety systems.
A single module executes safety logic, manages up to 64 mixed I/O channels, and supports hot-standby redundancy with < 50 ms switchover.
Functional Characteristics
• Architecture: Dual-core Intel 386EX, 32-bit, 25 MHz, lock-step synchronized
• Memory: 1 MB Flash (OS), 1 MB Flash (application), 1 MB SRAM (data)
• On-board I/O: 8 × configurable DI/O (analog optional)
• Scan Time: ≤ 20 ms for 1 000 certified safety blocks
• Communication: 2 × isolated RS-485 (Modbus RTU/ASCII), expandable via F8627X Ethernet module (Modbus TCP, Profinet, OPC UA)
• Diagnostics: 4-digit LED display + status LEDs (CPU, Memory, Comms, I/O)
• Redundancy: Dual 24 V power inputs and dual CPUs (< 50 ms failover)
Electrical & Environmental
