I'm looking for help. My employer (sysint) gives me questions that he knows I don't have the answer for. My homework is to find the answer and get back to him. He will ask everyday untill I get one. This question is about a week old. If I had a choice why would I want a 4-20ma over a 0-10vdc signal? If anyone could point me in the direction for this info I would appreciate it.
