ATD Automatic Timer Disconnect

BLUE SEA SYSTEMS7615
Can be configured to be used as one of the following battery saving productsTimer Disconnect - 12V signal triggers relay to connect battery power to devices - When signal is removed the timer is activated and will disconnect devices after a preset time - Timer ranges from 15 minutes to 4 hours Low Voltage Disconnect - 12V signal triggers relay to connect battery power to devices. - After 12V signal is removed, device senses low battery voltage and automatically disconnects devices. - Low voltage setting can be used in conjunction with Timer Disconnect. Low voltage will disconnect devices prior to preset time to preserve battery power Automatic Charging Relay - Automatically combines two batteries when charging, and isolates them when discharging - Single side sensing design only monitors the voltage of the start battery - Ideal for auxiliary batteries that are AGM or significantly larger than the start battery Solenoid - 12V signal will connect or disconnect relay without any time delay
