Description
HIMA K9202B | Dual-Axial Rack Fan Module
Product Introduction
A rack cooling failure can put an entire control cabinet at risk—even when every processor and I/O module is still functioning normally. The HIMA K9202B is a rack fan module equipped with two axial fans, as identified in HIMA certification documentation. Its job is thermal management, not safety logic execution or signal processing.
HIMA’s documentation states that the K9202B is otherwise the same as the K9203A. Surplus-market listings associate the K9202B with order number 996920261 and commonly describe it as a 24 VDC cooling assembly. However, detailed electrical and airflow values vary across reseller listings, so the actual nameplate and applicable cabinet documentation should take precedence during replacement selection.
For maintenance teams supporting installed HIMA systems, the K9202B should be evaluated as a configuration-specific rack accessory. Confirm the complete part number, mounting arrangement, connector, fan condition, and cabinet compatibility before treating a surplus unit as a direct replacement.

Global Sourcing & Live-Test SOP
For a used or surplus HIMA , the inspection must establish more than basic fan rotation. Cooling performance, mechanical fit, and electrical compatibility all matter.
1. Inbound Verification
- Photograph the full nameplate and every visible part-number marking.
- Confirm , not K9202 or K9203A.
- Record the associated order number, serial number, and revision markings where available.
- Inspect both axial fans for damaged blades, debris, corrosion, or bearing wear.
- Check the frame, mounting points, guards, and connector for physical damage.
- Compare the assembly’s mechanical dimensions and mounting arrangement with the installed unit.
- Request traceability documentation where available; do not treat a seller’s “OEM” claim as proof of authenticity.
2. Controlled Power-Up and Functional Test
- Confirm voltage, polarity, and connector pinout from the unit’s nameplate or applicable wiring documentation.
- Use a controlled power source with current monitoring.
- Do not energize the module solely because a reseller lists it as 24 VDC.
- Confirm that both fans start and continue running.
- Listen for bearing noise, rubbing, or abnormal vibration.
- Monitor current draw and check for intermittent startup or stopping.
- Record applied voltage, measured current, and observed fan behavior.
3. Rack and Cooling Diagnostics
A running fan assembly is not automatically a serviceable replacement.
- Verify airflow direction against the cabinet’s cooling design.
- Confirm both fans operate consistently.
- Inspect the airflow path for restrictions.
- Check that the module’s frame and mounting points match the intended rack position.
- Verify any fan-monitoring or alarm function using the approved cabinet maintenance procedure.
- Do not bypass a cooling alarm or safety-system diagnostic to complete a test.
4. Extended Heat Run
For a unit sold as tested, perform an extended powered run under controlled conditions.
Monitor:
- Startup reliability
- Fan rotation consistency
- Abnormal noise or vibration
- Current stability
- Connector and wiring temperature
- Airflow consistency
- Unexpected fan stoppages
Record the test duration, supply voltage, measured current, and observed condition. Do not claim a 24-hour heat run unless it was actually performed and documented.
5. Final Preparation and Shipment
- Record the exact model and all additional markings.
- Photograph the assembly and connector arrangement.
- Document whether both fans were tested.
- Include available test results and condition details.
- Protect fan blades, connectors, and mounting points during shipment.
- Use suitable ESD-aware packaging where electronic monitoring components are present.
- Clearly state whether the item is new, used, refurbished, or tested surplus.
- Do not represent third-party inspection as HIMA factory certification.
Field Engineer’s Pitfall Guide
❗ Do not assume K9202 and are interchangeable
The suffix is part of the component identification. HIMA documentation identifies as a two-axial-fan rack fan and relates it to K9203A. Do not substitute another model based on appearance alone. Verify the exact assembly against the installed cabinet configuration.
❗ Do not rely on conflicting reseller specifications
Surplus listings vary in their stated dimensions, airflow, current draw, and temperature limits. Confirm the actual unit’s ratings and connector details before applying power or approving it for service.
❗ Cooling hardware is part of the system’s operating conditions
A fan assembly that physically fits may still have the wrong airflow direction, electrical characteristics, or monitoring arrangement. Verify the cooling configuration and applicable fan-failure diagnostics before returning the rack to service.
Intent-Driven FAQ
What is the HIMA ?
The HIMA is a rack fan module with two axial fans. HIMA certification documentation identifies it as otherwise the same as the K9203A.
Is the HIMA a safety PLC or I/O module?
No. The is a cooling accessory. It supports rack thermal management rather than performing safety logic processing or field signal acquisition.
What voltage does the HIMA use?
Secondary supplier listings commonly report 24 VDC. Confirm the rating and polarity on the actual unit or in the applicable HIMA cabinet documentation before energizing it.
What is the associated order number for the ?
Surplus-market documentation associates with order number 996920261. Verify that marking against the physical unit before purchase.
Is the interchangeable with the K9203A?
HIMA documentation states that is otherwise the same as , while identifying as the two-axial-fan version. Confirm the required configuration and applicable documentation before approving a substitution.
Can the HIMA be hot-swapped?
Do not assume hot-swap capability. Treat replacement as a power-off maintenance task unless the specific system documentation explicitly authorizes live replacement. Follow the site’s safety and cabinet-maintenance procedures.
What should be checked before buying a used ?
Confirm the exact model, additional order-number markings, fan count, electrical rating, connector, mounting arrangement, physical condition, and supplier test status. Request clear photos of the nameplate and complete assembly.
Bottom Line for Buyers
The is an OEM-identified dual-axial rack fan module intended for control-system cooling. HIMA documentation establishes its basic identity and its relationship to , while detailed electrical and performance ratings still require confirmation against the specific unit.
For procurement, request photographs of the nameplate, both fans, mounting frame, and connector. Confirm the cabinet’s required configuration and obtain documented test results before treating a surplus as a service-ready replacement.
