Hello to all users, I am new to this type of construction and I need your help, indeed make the connection of a relay in order to supply the cooling pump and my problem is the connection of this last on the UCBB board. If I understood correctly, the relay card is supplied by the GND and the VCC in 24 volts (do not take into account the relay which is in 5v, waiting for an order) the IN1 contact allows to supply the coil by connecting to the GND, but how should I connect it to ucbb
Thank you for your patience
cordially
patrick
