Help! No voltage on Beckhoff output terminal

2 posts in this topic

I am trying to open a valve with a 24v digital output terminal (EL2828) on my Beckhoff CX9020.  I got the code working and the diagnostic LED lights up on the terminal when I want it to.  The problem I have is that there is no voltage coming out of the terminal and going to the valve.  Any ideas on what the problem could be?

Do you check the terminal output by voltmeter? Please send your wiring diagram. By the way, you should also feed the + and - terminal on the CX9020 to have 24 V for your output terminals.
