This lets a single alternator, shore charger, or solar controller keep multiple battery banks topped up without manual switching, while protecting the engine-start battery from being drained by house loads. The 7611 is rated for a 12\/24V DC auto-ranging voltage input, so the same relay works correctly on either a 12 volt or a 24 volt system without configuration. It uses an electromechanical, quick-connect contact design with silver contacts for reliable, low-resistance switching, and operation is fully automatic based on sensed voltage at each battery bank. An integrated LED indicates the ACR status at a glance, and the housing includes side and bottom knockouts for cable connections, simplifying installation in tight helm, engine bay, or battery compartment spaces. Built for continuous marine duty, the relay carries a 120 amp continuous current rating with a 210 amp intermittent rating, giving it headroom for charging surges and simultaneous loads. The 7611 is finished in black and yellow for easy identification among other electrical components onboard. It is designed as a drop-in battery combiner for boats running dual-battery or house\/start battery configurations that need automatic, hands-off combining logic.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 7611\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current Rating:\u003c\/strong\u003e 120 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntermittent Current Rating:\u003c\/strong\u003e 210 Amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Input:\u003c\/strong\u003e 12\/24 Volt DC, auto-ranging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage:\u003c\/strong\u003e 1440 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Quick Connect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Electromechanical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface mount or panel mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Mode:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage:\u003c\/strong\u003e 24 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Resistance:\u003c\/strong\u003e 100 Milliohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Switching Voltage:\u003c\/strong\u003e 12 Volts (DC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Terminals:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black, Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 632085076115\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.25 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Blue Sea Systems 7611 ACR do?\u003c\/strong\u003e It automatically combines a starting battery and a house battery bank whenever a charge source is present and connected loads do not exceed the charge input, then isolates the banks again once charging stops, so the 7611 keeps both banks charged without a manual battery switch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 7611 work on a 24 volt boat as well as a 12 volt boat?\u003c\/strong\u003e Yes.
