Egis Mobile Electric 8820-1390 XD Flex 2 Dual VSR/Mech Relay with Knob and 6-Pin DTM Connector

The Egis Mobile Electric XD Flex 2 Dual VSR/Mech (8820-1390) is a highly compact, 500-amp dual relay and Automatic Charging Relay (ACR) module designed to streamline multi-battery power management. By consolidating multiple heavy-duty relays and charge management functions into a single sealed, programmable unit, it dramatically reduces installation complexity and saves valuable space in any marine, RV, or powersports application.

This version features front-facing manual override knobs and a 6-pin Deutsch DTM connector for a secure, sealed plug-and-play wiring interface. Each knob allows you to force an individual relay open or closed, and can be locked in position for convenient servicing or load isolation.

Key Features:

• 500A continuous capability per relay — high-amp performance in an extremely compact footprint
• Dual VSR/Mech configuration — one position operates as a Voltage Sensing Relay (VSR/ACR) for automatic charge sharing; the other as a mechanical relay/battery disconnect
• 6-Pin Deutsch DTM connector — sealed, plug-and-play control wiring interface for reliable connections in harsh environments
• Front-facing manual override knobs — force each relay open or closed and lock position for servicing
• Bi-stable solenoid design — holds relay state without continuous power draw; ultra-low standby current of just 1.3 mA
• Programmable via dip switches — configure each relay as a standard relay/battery disconnect, Voltage Sensing Relay (VSR), or Low Voltage Disconnect (LVD)
• Remote ON/OFF/Auto inputs — force close, force open, or allow automatic voltage-sensing operation
• Local and remote LED indicators — front-facing LED shows real-time relay status; remote LED replicates local indicator
• IP67/IP6K9K sealed construction — fully weatherproof for mounting anywhere, including engine bays and exposed locations
• Stainless steel cable lug studs with self-locking flanged nuts for corrosion resistance
• Large mounting holes accept 1/4-20 or M6 hardware
• Wide voltage range: 8–36V DC auto-ranging, compatible with 12V and 24V systems
• Mechanical switching life: 1,000,000 cycles
• Max cranking current: 1,500A
• Expandable with Egis Link and Cross-Link busbars for 2- or 3-battery system configurations

The 8820-1390 is an ideal replacement for traditional solenoid-based battery management setups, replacing two individual high-amp relays with one compact module while eliminating external link cables and the risks of vibration-related connection failures.
