Hi,

You can use it to connect power supply or you can connect 4 pin power cable with 4-way screw terminal to setup your needs. Inputs and outputs are used for monitoring and controlling a connected device or receiving signals from that device in order to trigger certain events.

Please supply a practical example of what pin 3 and 4 can be used for. The it’s an input or output for attached equipment can be surmised, but in itself is a totally useless piece of information. A real world example of something connected to it and it’s practical use, would go a long way to define the contacts purpose. What are the technical requirements of input and output - current, voltage, frequency, duration, etc.

Thank you
