Since it is unusual to have more than 50% of the outputs on
at any one time, you can usually assume the system has a 250
ma output current capacity. If you are going to be turning on lots
of heavy loads at the same time, you should derate this to 150
ma.. This is sufficient to drive the majority of loads which will be di-
rectly connected to the outputs of the animation system. If addi-
tional 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. Coincidentally, boards for doing this are
available from Gilderfluke & Company. These include:
DPDT relay board: A set of eight electromechanical relays with
double pole/double throw contacts rated at 5 amps each.
Reed relay board: A set of eight small electromechanical relays
with normally open contacts rated at 150 ma each.
I/O module: A set of eight small solid state relays with normally
open contacts rated at 3.5 amps each (alternating current
