What is the maximum voltage i can get on arduino uno outputs. i need 10v output to use as a signal for a plc.

5V, but you can use a transistor or relay to switch a separate 10V power source to achieve what you need.

When I notice you talking about 10volts, I am guessing you want to conenct to the analog input of a PLC, is this correct?

Please provide clear and specific details of what you are wanting to do.


For using transistor as switch…
