The input LED for the optocouplers are internally connected to a series resistor of 1300
Ω
and are
limited to an input current of max. 20mA. For voltages of less than 11V a part of the series
resistance must be jumpered accordingly.
Note:
•
The input is configured for a maximum input voltage of 24 V DC and an input current of
maximum 20mA.
•
Reversing the polarity or overloading the input will destroy it.
