1.Product Positioning and Classification
The HIMA X-FAN 1803 is a fan module for HIMA safety control systems.It’s an optional accessory for the H41q/H51q series safety controllers,primarily used for heat dissipation and system redundancy.Its core functions include:
Active cooling:Provides forced air cooling for the controller’s internal electronic components(such as the CPU and communication modules),ensuring stable operation in high-temperature environments(such as those found in the chemical and oil and gas industries).
Redundancy:Can be combined with a backup fan module to achieve N+1 redundancy,preventing single points of failure from causing system downtime.
Environmental adaptability:Optimized for use in explosion-proof areas(Ex d/Ex i)or high-humidity/dust environments,it complies with international certifications such as ATEX and IECEx.2.Key Technical Specifications

3.Features
3.1 Intelligent Temperature Control and Redundancy Control
Dynamic Speed Control:A built-in temperature sensor automatically adjusts fan speed based on the controller’s internal temperature(e.g.,low speed below 40°C,high speed above 60°C).
Failover:If the primary fan fails,the backup fan immediately starts up and generates an alarm via the HIMA diagnostic system(e.g.,”FAN_FAIL”signal on the F8627A controller).
Hot-Swap Support:Faulty fans can be replaced while the system is running,eliminating maintenance downtime.3.2 Explosion-Proof and Environmental Adaptability
Explosion-proof Design:The housing is made of die-cast aluminum alloy with an anodized surface to prevent static electricity accumulation;the interface sealing level is IP66(dustproof and waterproof).
Wide Operating Temperature:Supports ambient temperatures from-20°C to+70°C(requires a heating module for use in extremely cold regions).
Vibration Resistance:Passes IEC 60068-2-64 vibration testing,suitable for installation on offshore platforms and near vibrating equipment.
3.3 Integration and Diagnostic Functions
LED Status Indicator:A green/yellow/red LED displays the fan’s operating status(e.g.,green=normal,red=fault).
Communication Interface:Supports RS485(Modbus RTU)or HIMA proprietary protocol,enabling upload of fan status to a DCS/SIS system.
History Recorder:Stores the last 100 fault events(including timestamp and fault type)for easy traceability and analysis.
