The DEIF RMP-112D Uni-Line is a dedicated protective overload and reverse power relay designed for generator and prime mover protection within marine power management and control systems. Conforming to ANSI Code 32, this relay continuously monitors 3-phase power flow and intervenes when overload or reverse power conditions threaten generator integrity. It occupies a critical role in shipboard electrical distribution panels, safeguarding generating sets and ensuring stable, uninterrupted power supply across vessel operations. As part of DEIF’s Uni-Line relay series, it integrates into marine control system architectures where reliable, fast-acting generator protection is operationally essential.
Key Features
✓ Provides overload and reverse power protection to ANSI Code 32 standard, with 3-phase measurement ensuring comprehensive monitoring of generator output under all load conditions.
✓ Configured for a 415VAC supply, 440VAC measurement voltage, 100% primary power rating of 715 kW, and a current transformer ratio of 1500/S — parameters set for the specific generator installation.
✓ LED indication for both alarm condition and activated relay output enables rapid visual fault identification at the panel, reducing diagnostic time during watch-keeping or fault response.
✓ Timer-controlled tripping provides adjustable response delay, preventing nuisance trips from transient fluctuations while ensuring protection activates within defined thresholds; mounting is via 35 mm DIN rail or base plate, subject to panel configuration.
✓ Relay outputs B and C are configured as normally energised (NE), making this unit a direct replacement or retrofit component — compatibility with existing DEIF Uni-Line installations should be confirmed against system drawings and nameplate data.
Marine Applications
✓ Generator protection panels aboard merchant vessels, tankers, bulk carriers, and container ships where DEIF power management systems are installed.
✓ Offshore support vessels and platform supply vessels requiring reliable reverse power detection to protect parallel-running generator sets during load sharing.
✓ Ferry and RoPax vessel electrical systems where continuous generator availability is critical to propulsion and hotel load management.
✓ Naval auxiliary and coast guard vessels utilising DEIF Uni-Line relay infrastructure for integrated switchboard protection and alarm management.
✓ Retrofit and upgrade projects on vessels with ageing generator protection systems, where standardised DIN rail mounting simplifies panel integration and reduces installation downtime.
Why Marine Engineers Choose
The DEIF RMP-112D Uni-Line combines proven ANSI Code 32 reverse power and overload protection with clear LED diagnostics, timer-controlled tripping flexibility, and a compact, rail-mountable form factor — making it a reliable, specification-matched solution for shipboard generator protection within DEIF power management environments.
Ideal For
Merchant vessels, tankers, offshore support vessels, ferries, platform supply vessels, and any commercial or industrial marine application operating DEIF Uni-Line generator protection and power management control systems.
Technical Support & Compliance
Technical support is available for remote troubleshooting, onboard commissioning guidance, relay testing, and retrofit or integration assistance for DEIF Uni-Line installations. To confirm compatibility and suitability for your specific application, buyers are encouraged to share nameplate photographs, the full part number (100054288.10), existing system drawings or single-line diagrams, the generator set model and rating, panel or switchboard model and software version where applicable, and vessel name or IMO number. All compatibility assessments and technical recommendations are subject to confirmation based on the information provided.
