HIMA X-BASE-PLATE-18-01 18-Slot Safety System Base Rack

Product Brief Description

The X-BASE-PLATE-18-01 is a 18-slot high-capacity system base rack developed by leading German functional safety automation manufacturer HIMA, belonging to the HIQuad X series Safety Instrumented System (SIS) product line. As the core hardware carrier of the HIMA HIQuad X safety control system, it provides stable installation, power distribution and bus interconnection support for up to 18 safety control modules including CPU, communication cards, analog/digital I/O cards and redundant power supplies. It is specially designed for large-scale high-risk industrial safety control scenarios, and is one of the most widely used high-density safety system base racks in the global industrial functional safety field.

Core Technical Specifications

• Manufacturer: HIMA Paul Hildebrandt GmbH, original German industrial functional safety grade production standard
• Product Category: HIQuad X series SIS system dedicated 18-slot safety system base rack
• Physical Parameters: All-metal reinforced industrial shell, net weight about 1.2kg, IP20 protection grade, fully compliant with power plant level anti-vibration and anti-electromagnetic interference standards
• Slot Configuration: 18 independent hot-swappable module slots, supporting mixed installation of CPU, communication, analog I/O, digital I/O and redundant power supply modules
• Safety Performance: Fully compatible with HIMA TMR (Triple Modular Redundancy) safety architecture, supporting SIL3/SIL4 highest safety level system configuration, the overall system diagnostic coverage rate up to 99.99%
• Bus Design: Integrated dedicated high-speed safety backplane bus, supporting high-speed data synchronization between redundant modules, and the maximum system response time is less than 10ms
• Operating Environment: -25°C to +70°C working temperature range, 0-95% non-condensing relative humidity, fully meeting industrial EMC anti-interference standards

Key Core Functions

• Ultra-High-Density Module Installation Support: The 18 independent hot-swappable slots on the base rack can carry up to 18 different types of safety control modules at the same time, supporting the system to run up to 32 independent safety application tasks simultaneously, which can meet the complex safety control demands of large-scale industrial production processes, and effectively save more than 40% of the control cabinet installation space
• Integrated Redundant Power Distribution: The backplane of the base rack is designed with independent redundant power distribution circuits, which can stably supply power for all modules in the rack. Even if a single power supply module fails, the system will not be interrupted, ensuring the continuous and stable operation of the safety control system
• High-Speed Safety Backplane Bus: The dedicated high-speed safety bus inside the base rack can realize microsecond-level data synchronization between the three redundant CPU channels, and support real-time data comparison and voting of the TMR architecture, ensuring that the system can quickly make correct safety judgment actions when a dangerous situation occurs
• Full Self-Diagnostic Capability: The base rack is integrated with independent backplane circuit diagnostic function, which can real-time monitor the health status of each slot power supply and bus communication, and the fault information can be accurately displayed on the system workstation, helping maintenance personnel quickly locate abnormal points
• Perfect Thermal Compatibility Design: The base rack is specially designed with reserved air duct structure, which can be perfectly matched with the dedicated X-FAN 18 01 redundant cooling fan module, providing forced air cooling for all modules in the rack, ensuring that the system can operate stably for a long time even in high-temperature industrial environments

Typical Application Scenarios

• Petrochemical industry: Large-scale refinery emergency shutdown system (ESD), burner management system (BMS) and fire and gas detection system (F&G) safety control
• Power industry: Safety control of large heavy-duty gas turbines and steam turbines in thermal power plants, and safety protection of nuclear power plant conventional island process systems
• Natural gas industry: Safety control of large centrifugal compressors for long-distance transmission trunk lines and LNG receiving station process safety systems
• Metallurgical industry: Independent safety protection for large blast furnaces and rolling mill equipment in steel plants

Installation and Maintenance Guidelines

• Strictly implement anti-static protection before installation: operators must wear reliably grounded anti-static wrist straps to avoid static electricity damaging the precision backplane bus circuits inside the base rack
• The installation must strictly follow the HIMA official slot allocation specification, and the redundant CPU, power supply and communication modules must be installed in the designated slots to ensure that the system redundancy architecture meets the SIL3 safety certification requirements
• After all modules are installed, perform full system diagnostic test through the dedicated HIMA SILworX engineering software to confirm that the backplane bus communication and power distribution functions of all slots are completely normal
• Regularly check the operation status of the supporting X-FAN 18 01 cooling fan module during daily operation, and clean the dust accumulated on the surface of the base rack every 2 years, which can effectively extend the service life of this safety base rack to more than 20 years

Market and Supply Status
