Automātiskais lādēšanas relejs BatteryLink™ - 12/24 V DC 120 A

The BLUE SEA BatteryLink™ 7611 automatic charge relay is a device designed to optimize battery management in 12V or 24V DC electrical systems. It automatically combines and isolates starter and auxiliary batteries.

Its main function is to automatically combine batteries during charging and isolate them during discharge. This allows sharing a single charging source, ensuring both battery banks receive adequate charge without manual intervention.

The BatteryLink™ 7611 has a DC current capacity of 120 amperes (120A). It can also handle an intermittent current of 210 amperes for 5 minutes.

Yes, the BatteryLink™ 7611 is fully sealed and rugged. It is IP67 certified, meaning it is protected against immersion up to 1 meter for 30 minutes.

This relay is CE marked and meets the following standards for external ignition protection:

ISO 8846 UL 1500 SAE J1171

The BatteryLink™ 7611 has a voltage drop ten times lower than a traditional battery isolator. This results in batteries being charged more fully.

Yes, it includes an LED that indicates its status. The LED is lit when batteries are combined and off when they are isolated. It also provides an optional output for a remote LED.

The BatteryLink™ 7611 automatic charge relay is designed to operate with 12V DC or 24V DC electrical systems.

This is an optional function that keeps combined batteries at a higher voltage (up to 12.25V for 12V systems or 24.5V for 24V systems) while the engine is running. It allows extended use of auxiliary loads without risking a flat start battery.

To prevent corrosion of the connection wires and terminals, it is recommended to install the relay in a dry and protected location if possible. Avoid mounting it directly above the battery banks.

Before starting the installation, it is crucial to disconnect all battery connections to avoid any electrical risk.

You must connect one battery bank to stud terminal A and the other battery bank to stud terminal B. The quick-connect terminal marked Ground must be connected to the DC system ground via a 1 A inline fuse.

To temporarily activate this function, connect a wire from the Aux. Battery Priority quick-connect terminal via an inline fuse (one to ten amps) to a terminal or wire coming from the ignition switch that provides +12/24V DC when the ignition is on and 0V DC when the ignition is off.

To enable this function permanently, connect a wire from the Aux. Battery Priority quick-connect terminal through an inline fuse (one to ten amps) to a constant +12/24V DC source.

Yes, the relay has an optional output for a remote LED that mirrors the status of the built-in LED. To connect it, wire the red wire of the LED to a 12/24V positive source via a 1–2 amp inline fuse, and the yellow wire of the LED to the quick-connect terminal marked LED.

No, the 7611 relay is not designed to handle starting currents. If batteries need to be combined for emergency starting, it is recommended to use a battery switching system with a combine/parallel function.

Yes, the BatteryLink™ ACR has dual sensing, meaning terminals A and B are interchangeable. The relay operation will not be affected by swapping the starting and service batteries relative to the installation diagram.

Yes, with a continuous capacity of 120A, the BatteryLink™ 7611 is designed to handle high-efficiency alternators.

The manufacturer, Blue Sea Systems, warrants its products for as long as you own them.
