Technical Specifications 24VDC power supply; integrated fan speed monitoring circuit; rack plug-in structure; part code 996920302; fault relay output.
Functional Features Forced cooling for safety rack; fan rotation monitoring; fan failure alarm; dust filter; vibration resistant design.
Application Scenarios HIMA HIMatrix safety system, SIS safety cabinet in chemical, energy and power generation industry.
Performance Parameters High airflow capacity; real-time fan health monitoring; reliable long-term continuous operation.
Structural Characteristics Metal housing, built-in cooling fan, speed feedback sensor, status LEDs and rack backplane connector.
Working Principle Provide forced convection cooling inside HIMA safety rack. The built-in sensor continuously detects fan speed and sends fault alarm once abnormal rotation is detected.
Installation Requirements Insert into dedicated fan slot of HIMA rack; check airflow path; keep cabinet door closed during operation.
Usage Notes Cut off power before removal; inspect dust filter periodically; test fan alarm function in scheduled maintenance.
