Description

HIMA  F8650X  high-performance central CPU module

Processor: It adopts a dual-core Intel 386EX microprocessor, 32-bit, with a main frequency of 25MHz. It supports task-level redundant synchronization. The handover time in case of single-core failure is less than 50ms, meeting the requirements of IEC 61508 SIL3 certification.
Memory: 1MB Flash-EPROM is used for storing the operating system and user programs, 1MB SRAM is used for data storage, supports hot backup redundancy, and the data synchronization cycle of the master and slave cpus is less than 10ms.

Communication interface: It provides 2 RS-485 serial interfaces, with electrical isolation. The baud rate is selectable at 9600/57600bps and supports Modbus RTU/ASCII protocols. Reserve the Ethernet expansion interface. When combined with the F8627X communication module, it can support the Modbus TCP/IP protocol.
Electrical parameters: Powered by 5V DC, peak power consumption 10W, built-in overvoltage/overcurrent protection circuit, working voltage range 4.75V – 5.25V.

Environmental adaptability: The operating temperature ranges from -20 ℃ to + 60℃, with IP20 protection grade, anti-electromagnetic interference grade EN 61000-6-2 (level 4), and can withstand 95% humidity and strong vibration environments.

The F8650X is equipped with a triple redundancy safety architecture including processor redundancy, communication link redundancy and power supply redundancy. It also has intelligent diagnosis and fault-tolerant functions, supports multiple programming languages of the IEC 61131-3 standard, can be expanded for I/O through the HIMA H51q bus, and is compatible with multiple mainstream industrial protocols. It is applicable to multiple industries such as petrochemicals, power, water treatment, and metallurgy.
