simultaneously
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 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 anima-
tion system. Coincidentally, boards for doing this are available from Gilderfluke & Company. These in-
clude:
DPDT relay board: A set of eight electromechanical relays with double pole/double throw con-
tacts 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 (AC and DC relays available).
Solid State Relay Fanning Strip: For connecting up to eight popular Ôhockey puckÕ style relays to a
1/4 J-6 output cable. These are available with capacities of up to 75 amps each.
