Key Features & Benefits
1.Marine-Grade Protection: Constructed with corrosion-resistant materials, it effectively withstands salt spray, humidity, oil mist, and continuous vibration.
2.High-Density & Modular Design: Compact DIN-rail mounting allows for efficient use of control panel space. The modular design supports easy installation, replacement, or expansion of industrial-grade relay modules without rewiring the entire system.
3.Enhanced Reliability & Diagnostics: Features industrial-grade relays with clear contact ratings for long electrical life. A transparent or hinged cover provides quick visual status checks, while clearly labeled terminals simplify wiring, testing, and troubleshooting.
4.Simplified Installation & Maintenance: Includes pre-drilled mounting holes and standard cable gland entries for secure and watertight cable routing. The organized layout reduces installation time and facilitates easy access for maintenance.
5. Secure Electrical Isolation: Provides critical isolation between low-voltage control signals (e.g., from PLCs) and higher-power actuator circuits (e.g., motors, pumps, lights), protecting sensitive electronics from surges and interference.
Typical Applications
Automated control of engine room auxiliary machinery (pumps, fans, compressors).
Switching and control circuits for deck machinery, winches, and cargo systems.
Marine lighting control (navigation lights, floodlights, interior lighting).
Alarm and monitoring system signal expansion.
Power distribution and control on offshore platforms and port equipment.
Engineered for durability and performance, the FR-100 Marine Relay Box is the trusted solution for safe, organized, and reliable electrical control in harsh maritime conditions.
