This is for a work/hobby project. The voltage will be stuff oneself an submit upon a DDC. we am office building a modular exam pack which provides a open/closed, 0-10K, 0-10dc or 0-5dc(I arbitrarily chose 0-10 it can be either) voltage. we attempted to make use of a pot though it blew a compound in my source. I’m contrast with a portable vigilance generator. Would regulating a battery as a source compromise a problem? If so where would we suggest to purchase. For a alternative variations of submit signals I’m regulating an additional pot in together with a DPDT (on,off,on) switch which switches in between a voltage input, varying resistance, as well as when a pot is at max R on/off binary signal. Any suggestions?
DDC is approach digital controls. http://en.wikipedia.org/wiki/Direct_Digital_Control
