1. Modular Safety Control Platform
The Honeywell FS-BLIND-CHAS 3HE is a high-availability chassis engineered for centralized safety systems requiring SIL 3/PL e compliance per IEC 61508. Designed to house Honeywell FS-BLIND controllers and I/O modules, this 3U rack-mountable enclosure (EIA-310-D compliant) provides 8 modular slots for redundant configurations. Its reinforced steel construction delivers 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 40ms holdup time. Certified for -40°C to +85°C operation, it features intelligent thermal management with N+1 redundant fans and thermal zoning. Front-accessible multicolor LED indicators display power, fault, and module health, while EMC-shielded backplanes ensure signal integrity in electrically noisy environments. Designed for oil/gas ESD systems, turbine protection, and robotic safety, this chassis achieves 99.999% availability with automatic load balancing and fault-tolerant architecture.
2. Critical Technical Specifications
This chassis accommodates 8 FS-BLIND modules with ≤100ns slot-to-slot latency via high-speed backplane. Power specifications: Dual 100-240V AC inputs (50/60Hz), 24V DC output (25A max), ≤1.5kW consumption, and 40ms power holdup. Cooling system features 3× 60mm PWM fans (N+1 redundancy) with ±1°C temperature control. Physical dimensions: 133.35mm (3U) × 482.6mm (19") × 400mm depth supporting 25kg max load. Connection includes front-access RJ45 ports, USB-C engineering interface, 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 ISO 13849-1 PL e. MTBF exceeds 500,000 hours at 40°C (IEC 61709).
3. High-Risk Industrial Applications
This chassis serves critical safety functions including offshore platform emergency shutdown (ESD), turbine overspeed protection (API 670), and robotic workcell safeguarding. It supports chemical plant HIPPS, pharmaceutical sterilizer overpressure protection, and automotive stamping press controls. Additional applications include mining ventilation trip systems, compressor station safety interlocks, and power distribution bus differential protection. Its 3U form factor optimizes rack space 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.
