HIMA HIMax X-CPU31 SIS System Safety Processor Unit
HIMA HIMax X-CPU31 is an integrated safety processor module of the German HIMA HIMax Safety Instrumented System (SIS). X-CPU31 serves as the computational core of the entire safety system, executing safety logic operations, signal acquisition and judgment, safety interlock output, and achieving safety functions such as emergency shutdown and fire gas protection; Support redundant configuration, maintain uninterrupted system operation in case of hardware failure, ensure the safety of factory equipment and personnel, and be responsible for communicating with I/O modules and upper HMI/PLC to complete safe data exchange.

Product features
- Integrated design: The CPU and system bus are integrated into a single module, without the need to separately configure the X-SB01 bus module, reducing rack occupation of slots and lowering hardware procurement costs.
- SIL3 high security level certification: meets the IEC61508 functional safety standard, can be used for safety instrumented systems, supports redundant hot standby, and single point failure does not cause safety function failure.
- Compatible with the entire HIMax series: It can be paired with the full range of HIMax I/O cards to seamlessly integrate into the HIMax system, making system expansion and upgrading simple.
- Secure Ethernet communication: SafeEthernet secure communication supports distributed architecture, long-distance on-site secure data transmission, and strong anti-interference ability.
- Online maintenance without downtime: supports module hot replacement, maintenance, and firmware upgrades without shutting down the entire safety system, improving device availability.
- Built in full self diagnosis: continuously detects hardware and communication faults in the module, and the fault status panel LED displays intuitively, quickly locating problems.
- Adaptation to harsh working conditions: Meets ISA G3 anti-corrosion environmental standards and is suitable for dust and corrosive industrial sites in chemical, oil and gas industries.
Main product range
- Control system (DCS/PLC/CNC): panel controller, HMI and human-machine interface, industrial PC, CPU processor module, communication module, analog/digital I/O module
