Hello again guys,
I've read tons of informations on sinking and sourcing inputs and outputs, however there is something bugging me with this.
I want to connect a Banner TowerLight to my PLC to light its light (fun incomming). Here is an image of the wires:
I have my output card, which is a SOURCING one. Therefore, I know that my output card will send current to the towerlight to light its light. So, I think that I should go with the sinking connection, so NPN.
However, I check the picture and I don't understand how it works. I will connect my pin 3 to my 24 VDC and the rest of the colors (pin 4-1-2-5) will be connected to the PLC outputs. So, when I will activate my output, it will send current to the colors but where will that current sink if my blue cable (pin 3) is connected to the 24 VDC ? Shouldn't it be connected to the ground ?
Thanks a lot,
luisarcher.
