Hello,

Thank you for your question.

For temperature sensors we would recommend 3 wire sensor.  (Your b choice)

For connection you would need to use 1WIRE Power, 1WIRE Data and "Ground" (FMB sockets/wires)

Usually RED wire is for Power, BLACK for ground and the one that left is Data. But to be sure please read the manuals of your sensor. 

For your "Current transformer" sensor, you should connect it to Power supply(+) and Negative source (ground)

But once more, for that please make sure by reading your sensor manuals/instructions.

Best regards
