Egis Mobile Electric 9821-8530 XD NMEA 2000 Dual Relay/VSR with Knobs 8-Pin DT Connector

The Egis Mobile Electric XD NMEA 2000 Dual Relay/VSR with Knobs is a high-power, dual-circuit electrical management module engineered for demanding marine and mobile applications. This compact unit combines two independent high-amperage switching circuits — configurable as a remote battery disconnect relay and/or a voltage-sensing relay (VSR/ACR) — into a single sealed module, replacing two individual relays and eliminating the cost and risk of external link cable connections.

Fully integrated with NMEA 2000 networks, the XD Dual allows for remote switch control, real-time status monitoring, and battery voltage readings directly from compatible chartplotters and displays. The sealed 8-pin Deutsch DT connector provides a robust, weatherproof wiring interface.

Key Features:

• Dual-Circuit Design: Combines one relay and one VSR/ACR in a single module, supporting independent load switching and automatic charge sharing between two battery banks
• High Current Capacity: Rated for 500A continuous and 1,500A maximum cranking current, supporting all standard marine and mobile electrical systems
• Manual Override Knobs: Intuitive 3-position knobs allow manual forcing of each relay to Open or Closed and lock them in place, with clear indication of override state
• Bulletproof Construction: Sealed to IP67/IP6K9K standards with high-temperature electronics, corrosion-resistant stainless steel cable lug studs, and large mounting holes accepting 1/4-20 or M6 hardware
• NMEA 2000 Integration: Control and monitor via the vessel's NMEA 2000 network, or operate through discrete analog inputs for flexible installation
• Simple DIP Switch Programmability: Configure NMEA 2000 instance numbers, battery selection, relay function, and more via on-board DIP switches — no software required
• Ultra-Low Off-State Current: Advanced bi-stable solenoid design draws only ~1.3mA off-state — 90–95% less than comparable systems
• Space and Weight Savings: Achieves 35–75% reduction in mounting space and weight versus multi-device legacy electrical system layouts
• Wide Voltage Range: Operates across 8–36V DC, compatible with 12V and 24V systems
• Expandable: Compatible with Egis Link and Cross-Link busbars to add additional XD Single, Dual, or Triple relay modules for larger multi-battery systems

The 9821-8530 ships with the 8-pin Deutsch DT connector for plug-and-play installation and is backward compatible with legacy Egis ML Series relay wiring harnesses. A protective terminal cover with label recesses is included for clean, organized wiring identification.
