Hello,
the answer is 25 (derived from your screenshot)
You will find it in the TO Option documentation follow: Application manual R911383774
Basically it depends on the dynamization source. The answer above is meant for the ctrX DRIVE TO Option card dynamization source as shown in the picture.
Used external dynamization sources, the amount is dependent of several factors lik:
Output voltage and possible max. current of the dynamization source,
allowed max. load capacitance of the dynamization source
capacitance and resistance of the cable,
TO input capacitance and resistance
which source your dynamization signals will be coming from?
