Blue Sea Systems 7615BSS Automatic Timer Disconnect Battery Management Relay 12V

The Blue Sea Systems 7615BSS Automatic Timer Disconnect (ATD) is a versatile battery management relay that can be configured for multiple applications to protect your battery system. This intelligent device monitors battery voltage and automatically controls power distribution to prevent battery drain while ensuring reliable starting power.

Four Operating Modes:

• Timer Disconnect Mode: A 12V signal triggers the relay to connect battery power to accessories. When the signal is removed, an adjustable timer activates and disconnects devices after a preset interval ranging from 15 minutes to 4 hours, preventing battery drain from forgotten accessories.
• Low Voltage Disconnect (LVD) Mode: Continuously monitors battery voltage and automatically disconnects devices when voltage drops below a preset threshold, protecting your battery from deep discharge damage. Can be used in conjunction with Timer Disconnect for dual protection.
• Automatic Charging Relay (ACR) Mode: Automatically combines two batteries for charging when voltage rises, then isolates them during discharge. Features single-side sensing that monitors only the start battery voltage, making it ideal for systems with AGM auxiliary batteries or house batteries larger than the start battery.
• Simple Solenoid Mode: Functions as a basic remote battery switch where a 12V signal instantly connects or disconnects the relay without any time delay.

Designed for marine, RV, and automotive applications, the ATD provides intelligent battery management to ensure you always have power when you need it. The adjustable settings allow you to customize operation for your specific system requirements.
