Hello everyone,

I am wondering how the Digital Output for DIO modules are connected. I need to replace an old system that was an open-collector Digital Output.
Behind the DIO, I will have relays with 24V common (I pilot the 0V with the DIO to switch them on).

The pdf is pretty limited in term of information and the drawing on the module itself seems to describe something not open-collector.

Is there any information available?
Thank you,

Torpi

Hi Torpi,

I checked with our hardware team and unfortunately it is not possible to use the outputs as open-collector outputs. You have to use a coupling relay for this.

OK! Thank you for your response!
