I do not see the post I tried to enter earlier. This is a second attempt so ignore it if it is repeated. I am trying to find a way to simulate an automotive battery charge discharge cycle. PLC outputs are rated 0 to 10 volts. Can I simply stack it on a 5 volt power supply like two batteries to offset it 5 volts? If not how do you recommend simulating 10 to 15 volt range.
