after long search, I found these very slim boards for Servo Control. Currently I have a bunch of semaphore signals originally from Viessmann, but their drives are consuming a hig power and do not operate reliably.
Long story short. I will buy and test these boards for operating with Servos. Do you see the perspective to command them (and the switching outputs) with turnout commands in future instead of F0, F1, F2... This will much better implement them in the accessories.
Thanks and best regards,
