Ok, let me try again:
I am using an MB2. The specs indicate the inputs can be 5V or 24V. The manual shows a representative circuit of internal 24V feeding through the isolator diode then to a resister (value not indicated) then to the input terminal. When the input is high (no current flowing), the voltage at the input pin will be 24V which will not work with 5V solid state logic.
How can you hook 5V solid state logic to the MB2 inputs.
I have sent two requests to the manufacturer with no response.
