Connect and MIO module outputs not working

[tehfade]

I've got a RevPi Connect S hooked up to a MIO. I need 24v out to drive two relays and for some reason I am having problems getting it.

I have attached a diagram of how I have it wired, as well as the MIO settings in Pictory. When wired as such, the pin of the X2 connector on the Connect that I have marked "RELAY CONTACT" is always +24v. I can see that the output bit is being toggled correctly in Codesys and using PiTest, and I think I can hear the clicking of a relay inside the Connect--but still that pin is always +24v.

Not only this, but the second relay, which I have attached to pin 1 of the X2 connector in the MIO is not turning on either. I can also see that this bit is being toggled correctly. The physical pin is also turning on and off, but something is wrong: I measure an open circuit voltage of 20-22v on this pin, and if a relay is attached to it, the relay does not switch on, presumably because there is not enough current. I found a post about this where two other people also observe this behavior, but a solution was not found: viewtopic.php?t=3539

Does anyone have any ideas what's going on here?

Hi tehfade, the following way is the best way to commission the MIO without errors.
Use the instructions to put the module into operation:

Before you use another program, test the input with piTest:

Take care of the correct pinout of the output and input. More about this here:
