3.1.1 12 Volt DC Power Input Module
The DL8000 accepts 12 Volts dc (nominal) input power from an
internally mounted AC/DC converter. The 12 volt DC output from the
AC/DC converter is connected to the BAT+ and BAT– terminals. The
base system (CPU, power input, and backplane) requires less than 70
mA. The Power Input module economizes power consumption using 3.3
Volts dc switching power that provides power to the DL8000 modules
via the backplane. The DL8000 requires 11.25 to 14.25 Volts dc for
proper operation.

The CHG+ and CHG– terminals comprise an Analog Input channel that
allows you to monitor a voltage, such as an external charging source
from a solar panel. These inputs are not normally used for the DL8000.
The AUX+ / AUX – terminals can be used to supply reverse-polarity-
protected source voltage to external devices, such as a radio or solenoid.
The AUXSW+ / AUXSW– terminals can be used to provide switched
power for external devices. The AUXSW+ is turned off when a
software configurable voltage is detected at the BAT+ / BAT–
terminals.
