HIMA K9203A 996920360 Integrated Rack-mounted Three-Fan Cooling Module

I. Basic Positioning
Brand: German HIMA (Black Horse), compatible with HIQuad X series SIL3 safety instrument system (SIS/ESD)
Full model: K9203A, original factory material code 996920360
Equipment Type: Rack-mounted integrated three-fan cooling module, providing forced air cooling for the entire HIQuad X control cabinet. It is compatible with the IO cards F-IOP01, F-CPU01, and F32 that you previously queried and can be used in the same cabinet.

 Hardware Structure and Electrical Parameters
Fan Configuration
Three industrial axial flow cooling fans are built-in, with an aluminum alloy integrated frame. The fans are installed in an embedded manner on the top of the cabinet.
Power Supply Specifications
Working power supply: DC24V (standard safety power supply for the control cabinet)
Rated current of the entire machine: 2A
Environmental Tolerance
Operating temperature: -20℃ ~ +60℃
Storage temperature: -25℃ ~ +70℃
Protection IP20 (installed in the cabinet)
Mechanical Dimensions
A long-strip cabinet air duct module, with standard rack hole installation. The tail end has a multi-core plug for quick connection, and no separate wiring is required.

 Core Functions
Whole Machine Forced Cooling
The HIQuad X system CPU, I/O gateway, and safety IO card generate a large amount of heat during long-term operation. The K9203A provides continuous air duct circulation to prevent the high temperature from causing incorrect actions, capacity reduction, or shutdown of safety components.
Fan Fault Monitoring
An internal fan speed detection circuit is built-in. If any fan stops rotating or has a low speed, a fault alarm will be uploaded to the F-IOP01 I/O bus module, triggering an upper-level alarm on the DCS.
Safety Redundant Cooling Design
Even if one fan fails, the remaining two can still maintain basic cooling. It does not trigger ESD shutdown for a short period, leaving a window for maintenance and spare parts replacement, in line with SIL3 fault-tolerant design.
Air duct dust-proof metal mesh cover, facilitating on-site cleaning and maintenance, suitable for dusty conditions in power plants, chemical plants, and petrochemical plants.

System Integration (Components in the Same Cabinet)
The complete HIQuad X safety rack is fully compatible with:
Cooling Unit: K9203A 996920360 (this cooling fan module)
System Power: F-PWR01
Triple Redundant Controller: F-CPU01
I/O Bus Gateway: F-IOP01 (984850100, the model you queried earlier)
Field Safety IO: F3237 DI / F3330 DO / F6217 AI
External Communication Card: F-COM01 (connects to ABB Symphony DCS)

Typical Application Scenarios
Fire power plant boiler MFT, turbine ETS emergency trip safety system
Chemical and petrochemical plant ESD emergency stop, F&G fire and gas interlock system
Natural gas, LNG station safety instrumented system
Integrated with ABB Symphony INFI90 DCS, GE 760 protection, and Woodward parallel module for unit safety interlock
