I put the question to which I have not been answered here:
I want to use the RUT955's power connector output port.
I need for example to connect a relay to the output (pin 4) of the Power Socket connector.
If for the other connectors the example of the open collector output (pin 3,4,8) is well explained here

I miss it, and I don't find in the wikis or in the diagrams a practical example for the output port (pin4) of the power connector, considering that pin 3 is an input and pin1,2 are power supply.

I hope I have explained, excuse for my poor english
Thanks in advance for the help
