Description

The EGIS XD Series Flex 2 Dual combines two independent 500A relay circuits in a single compact module, replacing two individual high-current relays and the cables that would link them. Configured as a switched relay plus an automatic charging relay (the voltage-sensitive relay, or VSR), it handles dual-battery load switching alongside automatic charge sharing between banks, and suits two and three battery systems. Each circuit is rated 500A continuous and 1500A maximum cranking across an 8 to 36 V DC range, covering standard 12V and 24V marine electrical systems.

Construction is sealed to IP67 and IP6K9K with high-temperature electronics, an integrated Gortex vent and stainless steel cable-lug studs that accept 1/4-20 / M6 hardware. Each circuit is dip-switch programmable under the included protective cover and carries a three-position manual override knob for clear, lockable open or closed control. Off-state draw is just 1.3 mA, front and remote LEDs report status, a 40-circuit weatherproof label set is included, and the Deutsch DTM connector is pin-for-pin compatible with legacy ML Series bi-stable relays. The system expands with 8790 link and 8791 cross-link busbars.

What is the difference between the relay and the VSR circuit?
The relay circuit is a basic switched relay for load switching, while the VSR (voltage-sensitive relay) is an automatic charging relay that combines two banks when a charge source is present and isolates them when it is not. Both share the same 500A rating.
How many relays does this module replace?
One XD dual replaces two individual high-current relays plus their interconnecting cables, cutting mounting space and removing the risk of link cables vibrating loose.
Will it work on both 12V and 24V systems?
Yes. The XD Series operates across an 8 to 36 V DC range, covering standard 12V and 24V marine electrical systems.
Can it be expanded for more batteries?
Yes. It accepts EGIS 8790 link and 8791 cross-link busbars to connect additional single, dual or triple XD relays for two and three battery systems.
