3. Key Product Features
3.1 Dual Microprocessor Redundant Design
The F8650X adopts a redundant configuration of dual microprocessors, which can automatically switch to the backup processor in the event of a single processor fault without manual intervention. This design maximizes the system’s availability and operational reliability, and ensures the continuous and stable operation of industrial safety control.
3.2 Industry-Leading Safety Performance
Fully compliant with the IEC 61508 international safety standard, it is a core safety component with SIL 3 and even SIL 4 ratings. It supports core safety functions such as emergency shutdown (ESD) and safety interlock, forming a solid safety barrier for critical industrial processes.
3.3 Rich & Versatile Communication Capabilities
Integrated with a full set of industrial communication interfaces including PROFIBUS, Ethernet and CAN, it realizes seamless data exchange and interconnection with various industrial equipment, DCS systems and upper monitoring platforms. The electrically isolated RS485 interface further improves the anti-interference ability of communication and ensures the accuracy of data transmission.
3.4 Real-Time Diagnosis & Intuitive Status Display
Built-in safety watchdog circuit, multi-group LED status indicators and 4-digit nixie tube display, which can monitor the running status of the module in real time. Once a fault occurs, it can quickly output accurate fault diagnosis information, helping maintenance personnel locate and solve problems efficiently and reduce equipment downtime.

4. Product Structure & Components
The HIMA F8650X adopts a highly integrated modular design, with clear functional division and stable structural performance, which is convenient for installation, debugging and maintenance:
- CPU Core: Dual-core microprocessor (Intel 386EX / PowerPC 604e), the core computing unit of the module, responsible for the operation of safety logic and real-time processing of industrial process data.
- Storage Unit: Classified storage of Flash-EPROM (OS and user program) and SRAM (real-time data), ensuring data security and fast reading/writing speed.
- Communication Module: Integrated professional industrial communication interface circuit, supporting multi-protocol data transmission and realizing seamless connection with the industrial control network.
- Power Supply Module: High-efficiency power conversion unit, which stably converts external 24V DC power into 5V/2A working power required by the internal circuit, with overvoltage and overcurrent protection functions.
- Human-Machine Interface (HMI): Combined with nixie tube and LED indicator, it provides intuitive visual feedback of module running status (power on, normal operation, fault, communication, etc.), and is easy for on-site operation and monitoring.
