Anyone have any suggestions on outputting 12VDC rather than 5 on the digital output? This output will be from the PID control and I will also need an output from the onboard relay to run simultaneously.
You would need an extra transistor to do this.
If you are using a 12V input power, you could tap this (VIN) on the breakout pins available on the output card.
Some wiring is needed to add this circuit.
Is this “output” identical/synchronize with the on-board relay output?
