Description
DEIF
TYPE: AAL-111Q96/1
INSULATION MONITOR
NO.: 410844.90
MONITORED AC-NETWORK: 0-528 VAC
The DEIF AAL-111Q96/1 is a panel-mounted insulation monitor designed for continuous monitoring of unearthed AC networks in marine electrical systems. Operating across a monitored AC network range of 0–528 VAC, this unit provides early detection of insulation faults, helping protect personnel, equipment, and vessel electrical infrastructure. As a core component within a Marine Control System, it plays a critical role in ensuring the safety and reliability of onboard power distribution.
Key Features
✓ Continuously monitors unearthed AC networks across a rated range of 0–528 VAC, providing real-time insulation fault detection.
✓ Panel-mount form factor (96mm format) suitable for integration into standard marine switchboard and control panel cutouts.
✓ Designed for compatibility with DEIF control and monitoring systems, subject to confirmation of system configuration and software version.
✓ Supports installation in main switchboard, emergency switchboard, or distribution panel environments typical of marine electrical arrangements.
✓ Replacement and retrofit suitability should be confirmed against the original system layout, nameplate data, and existing wiring configuration prior to installation.
Marine Applications
✓ Main and emergency switchboards aboard merchant vessels, tankers, bulk carriers, and offshore support vessels requiring insulation fault monitoring.
✓ Onboard AC power distribution networks where earth fault detection is critical to crew safety and equipment protection.
✓ Integrated marine control and monitoring systems where insulation status forms part of the vessel’s alarm and safety logic.
✓ Diesel-electric and hybrid propulsion vessels where unearthed network integrity monitoring is essential to drive train protection.
✓ Newbuild and retrofit electrical panel installations requiring a reliable, purpose-built insulation monitoring device from a recognised marine automation manufacturer.
