May I know why there are 2 gnd ports and 2 24V/12V ports for Controllino Maxi?

And I just realized that the 2 GND ports and 2 24/12V are not connected to each other, also only one GND is connected to gnd port at X1.

Are there any details on the schematics on how these ports are connected internally?

Hello Calvin,

the ports are there to simplify your cable harness if needed (for example you can continue from this ports to power other CONTROLLINO, use this port as common GND and power point, etc.). The ports are identical and are fully interconnected together.

Note: please take care, how you are measuring it, when the screws are not fully screwed, screw from the the top side has no contact. Try to fully screw and measure again ;-).

  Hello Jarda,
  
  Thank you for the answer, I will check if both ports are connected.
  
  May I know if you are part of Controllino employee?
  
  I am trying to contact via chat and email but no one is replying.
  
  Thank you!

      Hello Jarda,
      
      I am afraid that your team has not replied me for a month or so. Can you help me to check the email under my account here and reply to me?
      
      Thank you!

        Hello Calvin,
        
        I think the answer to your question is in on of the replies and I can confirm it:
        
        Both GND cand 24/12 clams are connected with eachother but you have to measure in the holes of the cables and not on the screws on top.

        Sorry Johi, I asked another question via email related to one of your CTO reply emails to me a few months ago that there will be a new product with RS485 and Analog Output. But I am not sure why I did not get any reply until now both from the chat platform and email info@controllino.com
        I don’t want to put my email address on forum, so if you are from controllino maybe you can take a look at my registered email address and check email from me.
        
        Thank you!
