HIMA K9202B (996920261) Energy-Saving Cabinet Fan Module – Reliable Cooling for Safety Control Cabinets
The HIMA K9202B (order no. 996920261) is a compact, energy-saving cabinet fan module designed to keep safety PLC panels and auxiliary control enclosures at a stable operating temperature. From my experience, this unit fits well in cabinets housing HIMax/HIQuad X systems or third‑party I/O, where consistent airflow and low noise matter. One thing I appreciate is the smart, no‑nonsense design: efficient fans, simple 24 VDC wiring, and a clean alarm contact you can land on your PLC or cabinet annunciator.

Key Features
- Energy-efficient airflow – Optimized fan curves deliver the required cooling with reduced power draw, which typically cuts cabinet energy losses.
- 24 VDC control-cabinet friendly – Runs on the standard 24 VDC cabinet supply, simplifying integration with existing safety systems.
- Alarm relay for monitoring – A dry contact (fan OK/fault) lets you track fan status in the PLC or DCS, reducing unplanned downtime.
- Low-noise operation – Designed for continuous duty next to sensitive I/O, keeping acoustic noise and vibration in check.
- Service-friendly layout – Filter mat and fan access are typically straightforward, so maintenance crews can swap parts fast.
- Stable cooling for safety electronics – Helps keep HIMA CPUs, communication modules, and power supplies within their ideal temperature band.

Application Fields
You’ll typically see the K9202B applied in safety-related and general automation cabinets where heat buildup shortens electronics life. It pairs well with HIMA safety PLCs but also supports mixed-vendor panels.
- Oil & gas process skids, burner management, and ESD cabinets
- Chemical and pharmaceutical batching lines with high I/O density
- Power generation turbine and balance-of-plant control rooms
- Rail, water/wastewater, and utility substations where ambient heat fluctuates
- Any enclosure running 24/7 where stable airflow protects CPUs, I/O, and power supplies
Advantages & Value
- Reliability – Continuous-duty fans and an alarm relay help you detect degradation before failure. In many cases, this prevents nuisance trips.
- Compatibility – 24 VDC supply and simple wiring make it cabinet-agnostic; it slots into safety, process, or MCC auxiliary panels with minimal change.
- Lower lifecycle cost – Better thermal control typically extends the service life of PLCs, relays, and PSUs, cutting replacement frequency.
- Supportable spares strategy – Standardized consumables like filter mats and fans keep maintenance predictable.
Installation & Maintenance
- Environment – Mount in a sealed control cabinet with adequate intake/exhaust path. Avoid corrosive gases and conductive dust. Maintain top/bottom clearance for airflow.
- Wiring – Feed from a protected 24 VDC source (proper fusing). Land the alarm relay on a spare DI for status. Ensure cabinet grounding is intact to minimize EMI.
- Safety – Isolate 24 VDC, wait for fan stop, and follow lockout/tagout before servicing. Verify rotation and airflow direction upon commissioning.
- Routine maintenance – Inspect filter mats monthly in dusty areas; replace when visibly restricted. Clean grills and check fan bearings quarterly. If a thermostat is used, validate setpoints during scheduled PMs.
A maintenance lead at a gas processing site told us the alarm contact “paid for itself” by flagging a slowing fan before a summer heat wave—no shutdown, no scramble.
Quality & Certifications
- CE compliance (LVD/EMC) for industrial environments
- RoHS-conform construction
- UL/cUL component recognition typically available for fan assemblies used in control cabinets
- Manufacturer’s standard quality system aligned with ISO practices
If you need a check against your cabinet’s heat load or want to confirm alarm wiring details for HIMA PLC inputs, share your panel layout and we’ll map the connections and airflow direction so commissioning goes smoothly.
