Hello,  
I am a student .In my final proyect have a ABB IRB 660 robot. For the job the robot needs activate some coils (Outputs).The robot have too some sensors (Inputs). I am doing somme plans of the electricals connections. One of this is a plane for the DSQC 652 wiring.I have a question about the polarity of the input and output signals. In the output case they are negative or positive? . I have the same question about the input signals.  
Due to COVID\_19 I can not go to class to try to check.

Regards.

Output rated voltage is +24 VDC, supply for outputs (to the DSQC 652) should be in the range +19 to +35 VDC.  
Inputs “1” = +15 to +35 VDC., “0” +0.35 to +5 VDC.

Tanks graemepauling for your answer.  
So if I connect the terminal of a coil to one of the output singnals of the module DSQC 652. The other terminal of the coil should be connect it to negative source isnt´it.

Regards.

To the 0 volt or earth of the controller if using the controllers power supply.
