Blue Sea 7615 Automatic Timer Disconnect

On sale $147.99 $99.47
Blue Sea Systems Automatic timer disconnect for 12 volt systems. Rated up to 120 Amps continuous load, 210 Amps for 5 minutes.This is a 12 volt relay that can be configured to operate in a variety of ways. The unique way it can be configured to operate is as a 12 volt timer disconnect. When the timer is triggered it can connect a battery to a load for a pre-programmed time from 15 minutes up to 4 hours. The trigger can be any 12 volt signal or it can be set up to be voltage sensitive. This device can be configured in other ways too that are not unique; it can be set up as a voltage sensitive relay, but there is already a similar device that does that and costs less. It can be set up as a low voltage disconnect, again there is another device that does that for less money. It can also be used as a straight relay without any need for a timer. So it is truly multifunctional.

This is a 12 volt relay that can be configured to operate in a programmable manner. First it can be configured to operate as a stand alone 12 volt timer disconnect. When the timer is triggered it can connect a battery to a load for a pre-programmed time from 15 minutes up to 4 hours. The trigger can be any 12 volt signal or it can be set up to be voltage sensitive. This function of the device can then be further modified in the settings. The three behaviors that can be customized for the ATD by setting all six DIP switches on the back side of the device are connect time, disconnect voltage, and charge sense


Can be configured to be used as a combination of the following battery saving products:

Timer Disconnect 
A 12V signal triggers the relay to connect battery power to devices.  When signal is removed the timer is activated and will disconnect devices after a preset time.  The Timer ranges from 15 minutes to 4 hours, the increments available are 0 seconds, 5 seconds, 15 minutes, 30 minutes, 1 hour, 1.5 hours, 2 hours and 4 hours


Low Voltage Disconnect 
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.  The increments available are 11 volts, 11.5 volts or 12 volts.  This function can be disabled if required.

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. This function can be disabled if required.

Solenoid 
12V signal will connect or disconnect relay without any time delay. This is achieved by setting the time delay to zero.


Detailed setup

This device has a lot of possibilities in how it gets used, the best way to understand the details is to read the instruction manual.
