I have a Automation Direct PLC Do-06DR. DC inputs sinking or sourcing. I am switching 0VDC to the inputs and the +24VDC is connected to the input commons. I belive this means the inputs are sourcing. Which CR9321 current switch would I use? How would it turn on with only 0VDC at its input and the other wire going to the plc input?

Dear Sir, Thank you for your interest in our product lines. The NPN output pulls the input low. You will need our CR9321-NPN for your application.
