Description
- Technical Specifications:
Model Series: 94 Series
Part Number: 947022-16-11
Explosion Protection Grade: Ex d IIC T6
Operating Temperature: -20 °C to +60 °C
Ingress Protection: IP66
Terminal Capacity: 16 circuits
- Functional Features: Concentrated connection of multi-channel cables; circuit isolation and anti-interference; adapt to complex on-site wiring layout; support field quick wiring.
- Performance Parameters: Maximum working voltage 690 V; rated continuous current per circuit 16 A; anti-electromagnetic interference performance compliant with EMC industrial standard.
- Material Composition: Outer housing: High-pressure die-cast aluminum alloy; Internal insulation: Flame-retardant PC engineering plastic; Conductive terminals: Oxygen-free copper; Sealing components: High-temperature resistant fluororubber.
- Structural Characteristics: Large-capacity internal cavity; layered wiring structure; overall full sealing; reinforced edge protection structure; integrated cable entry ports.
- Working Principle: The flameproof shell isolates internal electric arcs and heat sources from external combustible media; multi-layer insulated structure ensures independent operation of each circuit and eliminates cross-interference.
- Advantages & Highlights: 16-circuit large capacity; high flame retardant and explosion-proof performance; strong anti-interference; integrated cable entry design; suitable for dense wiring scenarios.
- Applicable Industries: Large petrochemical plants, oil refineries, gas storage stations, chemical synthesis workshops, offshore platform automation systems.
- Installation Requirements: Install in dry and ventilated hazardous zones; reserve sufficient wiring space around the module; all cable inlets must be sealed with matching explosion-proof cable glands.
- Usage Notes: Strictly follow rated current and voltage range; regular overhaul of internal wiring every 12 months; prohibit using in environments exceeding rated temperature; damaged modules must be replaced entirely.
