Egis Mobile Electric 9821-8350 Dual XD NMEA 2000 ACR/Relay Battery Management System 8 Position DT

The Egis Mobile Electric Dual XD is an advanced marine battery management system that combines an Automatic Charging Relay (ACR) and high-amperage relay in a single compact module with NMEA 2000 integration. This innovative dual-switch solution provides intelligent charge sharing between batteries while offering manual override control through integrated yellow knobs on the face of the unit.

Key Features:

• Bullet-proof construction sealed to IP67/IP6K9K standards for mounting in any environment, even exposed locations
• High-temperature electronics and materials withstand harsh marine conditions
• 500A continuous / 1600A cranking capacity per switch supports all standard marine electrical systems
• Stainless steel cable lug studs resist corrosion
• Large mounting holes accept 1/4-20 or M6 hardware for secure installation
• NMEA 2000 integration allows remote control and monitoring of switch status and battery voltage
• Flexible control options via NMEA 2000, discrete analog inputs, or manual knobs
• Intuitive manual override knobs provide clear awareness of locked on/off states
• Simple programmability via DIP switches for flexible relay function configuration
• 8-position DT (Deutsch) connector provides sealed, reliable wiring connections

Space-Saving Design:

• Advanced bi-stable solenoid design delivers 35-75% reduction in mounting space and weight compared to traditional systems
• Replaces multiple individual relays with one integrated module
• Expandable with Link and Cross-Link Busbars to connect additional Dual, Triple, or Single XD Relays
• Supports 2 or 3 battery systems with standard busbar interconnect accessories
• 90-95% less off-state current draw versus competitive products

Battery Management:

• Eliminates dead start batteries by sharing charging between two batteries when charge sources are present
• Automatically isolates batteries when no charge sources are detected
• ACR functionality ensures operationally critical batteries retain sufficient starting power
• Designed to replicate common dual battery load switching and charge management functions

The Egis Dual XD represents a significant advancement in marine electrical systems, combining robust construction with intelligent NMEA 2000 integration. The high-quality Gore-Tex vent regulates internal pressure to prevent moisture ingress while maintaining long-term reliability. This unit is ideal for vessels requiring sophisticated battery management with the convenience of digital switching and the security of manual override capability.
