FS-BLIND-CHAS-4HE Blind-Mate Rack-Mount Enclosure Industrial Tool-Free Durable 4HE

1. Centralized Safety Control Platform​

The Honeywell FS-BLIND-CHAS 4HE is a high-availability chassis engineered for mission-critical safety systems requiring SIL 3/PL e compliance. Designed to house Honeywell FS-BLIND safety controllers and I/O modules, this 4U rack-mountable enclosure provides ​19-inch EIA-310-D compatibility​ with ​12 modular slots​ for redundant configurations. Its ​reinforced steel construction​ supports ​IP40 protection​ while enabling ​hot-swappable module replacement​ during operation. The chassis integrates ​dual redundant power supplies​ (100-240V AC ±10%) with ​auto-failover​ and ​3kW maximum power distribution. Certified for ​​-40°C to +85°C operation, it features ​integrated cooling fans​ with ​N+1 redundancy​ and ​thermal monitoring​ to prevent overheating. Front-accessible ​LED status panels​ display power, fault, and module health, while ​EMC-shielded backplanes​ ensure signal integrity in electrically noisy environments like substations or welding facilities. Designed for oil/gas HIPPS, turbine protection, and automated manufacturing, this chassis delivers 99.999% availability with automatic load balancing and fault-tolerant architecture.

​2. Critical Technical Specifications​

This chassis accommodates up to ​12 Honeywell FS-BLIND modules​ (controllers/I/O) with ​high-speed backplane communication​ at ​​≤100ns slot-to-slot latency. Power specifications: ​Dual 100-240V AC inputs​ (50/60Hz), ​24V DC output​ (29A max), ​​≤3kW consumption, and ​40ms holdup time. Cooling system features ​3× 80mm fans​ (N+1 redundancy) with ​PWM speed control​ and ​airflow monitoring. Physical dimensions: ​177mm (4U) × 482mm (19") × 450mm depth​ with ​35kg max load capacity. Connection includes ​front-access RJ45 Ethernet ports, ​USB-C engineering ports, and ​rear cable management arms. Environmental ratings: ​5G vibration resistance​ (IEC 60068-2-6), ​15g shock tolerance​ (IEC 60068-2-27), and ​​≤95% non-condensing humidity. Safety certifications: ​UL 60950-1, ​IEC 62368-1, ​ATEX Zone 2/22​ (optional kit), and ​NEBS Level 3​ for telecom. MTBF exceeds ​500,000 hours​ at 40°C ambient (IEC 61709).

​3. High-Risk Industrial Applications​

This chassis serves as the backbone for safety-critical systems including ​offshore platform emergency shutdown (ESD)​, ​power generation turbine trip systems, and ​automotive press line safety controls. It supports ​chemical plant burner management, ​pharmaceutical sterilization vessel overpressure protection, and ​mining ventilation methane shutdown systems. Additional applications include ​robotic cell perimeter safeguarding, ​nuclear plant reactor trips, and ​aircraft test rig safety interlocks. Its 4U form factor enables deployment in standard server racks for control rooms, while dual power supplies ensure continuous operation during grid fluctuations. The chassis maintains SIL 3 integrity in applications where undetected failure could cause catastrophic incidents—such as refinery flare systems or high-pressure gas compressors—with automatic module failover and distributed load sharing across power domains.

​4. Functional Advantages​
