HIMA X-CPU

HIMA X-CPU 01 is a high-reliability safety controller developed by HIMA for the Safety Instrumented System (SIS) in the process industry. It complies with the IEC 61508/61511 functional safety standards and is equipped with redundant dual CPUs, self-test, and fault diagnosis functions. Capable of completing safety logic operations within 0.1 seconds, it is suitable for critical processes requiring Safety Integrity Level (SIL) 2-3.

Main Parameters

• CPU Architecture: Dual redundant 32-bit processors, supporting hot backup switching.
• Operating Temperature: -25 °C ~ +70 °C (wide-temperature version optional).
• Power Supply: Dual 24 V DC power input, with power failure detection.
• I/O Capacity: Each I/O sub-rack supports up to 16 I/O modules, compatible with multiple signal types such as discrete, analog, and counter signals.
• Communication Interfaces: Multi-protocol support including RS-485 Modbus RTU, Profibus DP, Ethernet OPC, and Modbus TCP, facilitating interconnection with DCS, PLC, and upper-level systems.
• Safety Level: Meets the requirements of SIL 2-3 (PL c-d), with a Safety Integrity Level (SIL) assessment report available.

Product Features

• Modular Design: The central rack, communication modules, and power modules are separated, and the number of I/O sub-racks can be flexibly increased or decreased, enabling easy system expansion and on-site maintenance.
• Dual Redundant Safety Architecture: Two sets of CPUs operate synchronously, and automatic switching is triggered in case of any single-point failure, ensuring continuous and safe operation of the system.
• Self-Test and Fault Diagnosis: Features start-up self-test, periodic self-test during operation, and fault log recording, helping to quickly locate problems.
• Multi-Protocol Compatibility: Built-in common industrial communication protocols such as Modbus, Profibus, and Ethernet OPC, enabling seamless connection with mainstream DCS and PLC systems.
• High-Reliability Hardware: Adopts industrial-grade components with an IP50 protection rating, adapting to harsh on-site environments.

Structure and Composition

• Central Rack: Includes dual redundant CPUs, a system control unit, slots for communication modules, and slots for power modules.
• I/O Sub-Rack: Each sub-rack can accommodate 16 I/O modules, supporting discrete input/output, analog signals, counters, and other signal types.
• Communication Modules: Provide interfaces such as Profibus DP, Modbus RTU, Ethernet OPC, and Modbus TCP, supporting fieldbus and Ethernet interconnection.
• Power Modules: Dual 24 V DC power supplies, with power failure detection and switching functions.

Typical Application Fields

• Process Safety: Used in the Safety Instrumented System (SIS) of process industries such as petrochemicals, natural gas, oil refining, chemicals, and power generation.
• Industrial Automation: Combined with DCS and PLC to implement safety functions, such as emergency shutdown and explosion-proof valve control.
• Functional Safety: Meets the requirements of IEC 61508/61511 for Safety Integrity Level (SIL) 2-3, suitable for high-reliability safety control scenarios.
• Specific Projects: For example, the circulating fluidized bed boiler burner management system and furnace safety protection system of Vietnam Gao’an Power Plant.

Key Points for Installation and Maintenance

• On-Site Environment Inspection: Ensure the installation location meets the IP50 protection level requirements, and the temperature and humidity are within the rated range of the equipment.
• Power Wiring: The dual 24 V DC power supplies must be connected to the power modules separately; check the polarity and grounding reliability.
• Module Plugging/Unplugging: Perform I/O module plugging/unplugging only when the power is off to avoid hardware damage caused by hot swapping.
• Communication Configuration: According to the fieldbus or Ethernet protocol, use the configuration tool provided by HIMA to set parameters such as node address and baud rate.
• Self-Test and Calibration: Perform a system self-test after the first power-on to confirm that all modules are in normal status; conduct regular functional calibration and fault log cleaning.
• Spare Parts Management: Keep spare parts for dual redundant CPUs, communication modules, and power modules on hand to enable quick replacement of faulty components and shorten downtime.
