The DEIF RMV-112D is a protective voltage relay module designed for continuous monitoring and protection of AC voltage supplies in marine control system applications. Operating on a 24V DC supply and measuring 380VAC lines, this relay provides critical overvoltage and undervoltage detection, safeguarding onboard electrical distribution systems, generator control panels, and power management installations. Its relay and analog output capability makes it a versatile protective device within integrated marine automation and control architectures where reliable voltage supervision is essential to operational continuity.
Key Features
✓ Protective voltage relay function with measurement voltage rated at 380VAC (<0.5mA), providing accurate and sensitive voltage supervision across AC distribution circuits.
✓ Powered by 24V DC supply (max. 2W, Class 2 circuit, fuse max. 4A), with UL rating specifying 24V DC Class 2 and 110VAC configurations; UL/CUL approval supports up to max. 450VAC.
✓ Relay outputs rated at max. 250VAC or 24V DC at 8A resistive, and analog outputs up to max. 10V, enabling flexible integration with downstream control and monitoring equipment.
✓ Modular 380V design supports installation within panel-mounted marine control system enclosures; compatibility with specific DEIF panels or controllers should be confirmed against system drawings and nameplate data.
✓ Suitable as a direct replacement or retrofit component within DEIF-based power management and generator control systems; exact fit and interoperability subject to confirmation based on system configuration and software version.
Marine Applications
✓ Generator control panels and power management systems aboard commercial vessels, where continuous voltage monitoring is required to protect alternators and distribution equipment.
✓ Main switchboard and bus-tie protection circuits on offshore support vessels, platform supply vessels, and similar electrically complex tonnage.
✓ Automation and control cabinets on ferries, RoRo vessels, and cargo ships where DEIF control modules are integrated into the vessel’s electrical management architecture.
✓ Voltage protection within auxiliary machinery control systems on tankers, bulk carriers, and container ships operating under class-approved electrical management frameworks.
✓ Retrofit and upgrade applications in aging vessel electrical systems where existing DEIF protective relay modules require replacement to restore full protective functionality.
