K9203A 996920360 safety-related auxiliary module

HIMA K9203A 996920360 is a safety-related auxiliary module under HIMA’s industrial safety system product lineup, specifically positioned as a redundant cooling fan unit (supplementing and clarifying the earlier ambiguous positioning of K9203). It is designed to provide stable heat dissipation for HIMA safety controllers, I/O modules, and other core components in safety instrumented systems (SIS), ensuring continuous operation of critical equipment in harsh industrial environments. Below is its integrated detailed information based on official technical documents and mainstream supplier data:

1. Core Technical & Electrical Parameters

Parameter Category	Specific Details
Power Supply & Electrical Specifications	- Power input: 24V DC (compatible with HIMA system’s redundant power modules, voltage tolerance: ±10%).- Power consumption: ≤15W (full-load operation, including dual-fan redundancy).- Protection features: Built-in overcurrent protection (limit current: 1A) and reverse polarity protection; prevents module damage caused by wiring errors or power anomalies.
Cooling System Configuration	- Fan structure: Dual redundant fan design (2 independent fans in parallel), supporting "N+1" redundancy operation. If one fan fails, the other automatically takes over to maintain heat dissipation efficiency.- Airflow & speed: Each fan provides an airflow of ≥30 CFM (cubic feet per minute) at a rated speed of 2800 RPM; ensures effective heat dissipation for dense module layouts in control cabinets.- Noise level: ≤45 dB(A) at 1m distance; low noise, suitable for control rooms and on-site cabinets with noise restrictions.
