How to implement an isolated connection matrix
I need to put current on up to 30 lines; one at a time. What kind of electronics solutions are there to this kind of problem.
I can't drive it directly with a microcontroller because I need 28 VDC.
Response to Comments:
- 28 VDC
- Less than an amp of current
- Only needs to switch as fast as a human can press a button. maybe a few times per second max.
