Current protection. transistors?
hi i am new with the basic stamp. I have a bs2/sx stamp. I can input
and ouput from it at TTL level. I want to be able to hook up
starters proxes and other type industrial equipment. do you have any
suggestions on current protection. I know the chip is good for only
50mA per 8 pins. If anyone knows of a certain type of transistor or
maybe Solid State relays would work. I appreciate your help.
thanks, mike

devices such as relays and motors with my BS2. I use ULN2803A chips.
http://jameco.com has them. Jameco part # 34315.
