Automatický spínací relé BatteryLink™ - 12/24 V DC 120 A

The BatteryLink™ 7611 automatic charge relay from BLUE SEA 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 continuous 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 complies with the following standards for external ignition protection:

ISO 8846UL 1500SAE J1171

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

Yes, it includes an LED that indicates its status. The LED is on when the 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 charge level (up to 12.25V for 12V systems or 24.5V for 24V systems) when the engine is running. It allows prolonged use of auxiliary loads without risking discharge of the starter battery.

To prevent corrosion of the connection wires and terminals, it is recommended to mount the relay in a dry and protected location if possible. Avoid placing it directly above 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 1A inline fuse.

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

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

Yes, the relay has an optional output for a remote LED that replicates the status of the integrated LED. To connect it, wire the red wire of the LED to a positive 12/24V 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 combining/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 support high-efficiency alternators.
