Figure 8: Possible internal power supply for the optocouplers
The input LED for the optocouplers are internally connected to a series resistor of 1290
and are
limited to an input current of max. 20mA. For voltages of less than 10V a part of the series
resistance must be jumpered (J1, J3, J5) accordingly.
