Hi,

Limit, Input and ExtInOut boards all have same opto-cuplers and resistors on the input sides.
In manuals for Limit and Input board max input voltage is 24 V without any need for additional external current limiting resistor as in ExtInOut board manual 12 V is max voltage and external resitor is needed for higher voltage (24 V).

Is there something I don't see or why is there difference between Input and Limit manuals and ExtInOut manual?

Input manual (2022/05/25 Rev1.0)
Limit manual (2022/05/31 Rev1.0)
ExtInOut manual (2022/08/22 Rev1.2)

Thank you in advance.
