Figure 9: Possible internal power supply for the optocouplers
The input LED for the optocoupler is internally connected to a series resistor of 3,74k
and is
limited to an input current of max. 6mA.
Note:
The input is configured for a maximum input voltage of 24 V
and an input current
of maximum 6mA.
Reversing the polarity or overloading the input can destroy the device.
Using internal and external voltage at the same time can destroy the reader.
