Notes:
•
The inputs are configured for a maximum input current of 24 VDC
and an input
current of maximum 20 mA.
•
Reversing the polarity or overloading the inputs will destroy them.
•
The Reader supply voltage must not be used to drive the inputs, since otherwise
additionally induced noise may reduce the effective reading range.
