Hi,
I am having a problem with a senior design project that I was hoping to be solved by some of the experts on the forums. What I need to do is have a voltage signal from a DAQ (basically a micro controller), and have it control a separate voltage source. The DAQ outputs 0-5VDC (that can be controlled in the programming) at a maximum of .02A, and I want it to be able to PROPORTIONALLY control a separate DC source with this signal that would provide more current at the same voltage (up to a maximum of 8A). The type of separate power supply is not important, as long as it is able to be proportionally controlled by the low-amperage signal from the DAQ, and can provide the current. The DAQ cannot provide the current I need to control the load, which is an electronic brake that operates from 0-12V. Any ideas/suggestions would be greatly appreciated, thanks for your time.
