Brown Provides a +5V source for driving relays or auxiliary devices. Fused with a self resetting Polyswitch
device. Maximum output current is 500mA total. This output is diode protected and not highly regu-
lated as the regulated voltage passes through a Schottky diode. Since V-forward of the Schottky diode
varies with current drain, the voltage will vary from a low of ~4.9V at 500mA to a high of 5.2V lightly
loaded.

Black Defaults to circuit ground. Power return for the 5V supply. This line can be used to drive a master relay
that turns on when the 9850 turns on. Or by moving JP6 to poisition 1-2, provides an Open Drain Relay

With 5V relays, no other
power supply is required for
driving relay coils. Other
5V devices such as lamps or
alarms can also be powered
by these lines as long as the
maximum current rating is
observed.
Driving higher volt-
age devices (up to 25V)
requires the use of an exter-
nal supply. JP6 should be in
its default position 1-4 to
provide a ground reference
to the relay power source.
Therefore only 4 outputs
(SP1-4) are available.
When the 9850 is DC pow-
ered, SP5 can be used since
the ground reference is
provided through the power
input.
