negative sides of the outputs. You connect the positive sides (usually the
red wires) of the four things you controlling to either of the two positive
ʻcommonʼ terminals in the middle. The ʻnegativeʼ sides of the four things
you are controlling (usually the black wires) are connected individually to
the four outputs. These are numbered 0 through 3.
There is no ʻgroundʼ screw terminal on the output ʻendʼ of the Br-
miniBrick4. You can pick up the ground at the power supply connection if
needed.
All outputs are open collector switches to ground. Flyback diodes are in-
cluded in the outputs for driving inductive loads. Power is supplied through a
diode and a solid state circuit breaker to the common pin(s) on the connector.
A safe level of current is 300 milliamperes simultaneously on each output.
This is sufficient to drive most small relays, valves and other similar loads di-
rectly. If fewer than four outputs are on at one time, then the outputs are rated
as follows:
The supply line for the outputs is PTC fused for 1 amp.

Since it is un-
usual to have
more than 50%
of the outputs on
at any one time,
you can usually
assume the sys-
tem has at least
a 500 ma output
current capacity.

this to about 300
ma.. This is sufficient to drive the majority of loads which will be directly connected to
the outputs of the animation system. If additional current capacity is needed, or if you
need to drive higher voltage loads, you can connect relays as needed to the outputs of
the animation system.
