FZA 160-12 Aküsan Technical Specifications and Industrial Applications
Decoding the FZA Series Controllers
When dealing with industrial control systems, the FZA 160-12 Aküsan represents a specialized solution for hazardous environments. Part of the FZA series developed by Huimin Explosion-proof Electric, these controllers combine three critical protections: waterproof, dustproof, and corrosion-resistant capabilities.
Core Technical Parameters
- Operating voltage: 12V/24V DC (customizable)
- Protection class: IP66/IP67 (environment-dependent)
- Temperature range: -40°C to +85°C
- Contact configuration: 1NO+1NC (16A rating)
- Housing material: Marine-grade aluminum alloy
Industrial Implementation Scenarios
In the petrochemical plant explosion-proof upgrade project at Zhenhai Refining Base, engineers replaced 142 traditional controllers with FZA-160 series units. Post-installation data showed:
| Metric | Improvement |
|---|---|
| Maintenance frequency | Reduced 68% |
| Failure rate | Decreased 82% |
| Mean time between failures | Increased from 8,000 to 23,000 hours |
Certification Compliance Matrix
The FZA 160-12 Aküsan meets multiple international standards:
- ATEX Directive 2014/34/EU (Zone 1/21)
- IECEx IEC 60079-0/1
- GB 3836-2010 (Chinese national standard)
- 3C certification for explosion-proof components
Customization Capabilities
Huimin's engineering team can modify:
- Contact material (AgSnO₂ or AgNi variants)
- Enclosure dimensions (±15% from standard)
- Terminal types (screw/spring/plug-in)
- Add auxiliary contacts or status indicators
Recent smart factory projects have integrated IoT modules into standard FZA controllers, enabling real-time contact wear monitoring through embedded sensors. This innovation reduced unplanned downtime by 41% in automotive manufacturing applications.
Installation Considerations
- Minimum bending radius: 8× cable diameter
- Torque specifications: 1.2-1.5 N·m for M20 cable glands
- Ambient humidity: <95% non-condensing
- Vibration resistance: 5-150Hz, 10g acceleration
When commissioning offshore wind turbine control systems, technicians discovered the FZA 160-12's salt spray resistance exceeded 2,000 hours in ASTM B117 testing – 35% longer than comparable European models.
