To connect a device with “open collector” output it is necessary to add a resistor 2..10 KΩ
(depending on acceptable output amperage) by the pic.13 scheme:
Pic.13. Connecting the “open collector” output device
To connect a device with optocoupled output use the following scheme (pic.14). It is
recommended to add a resistor to a optron collector’s circuit (resistor’s parameters are the same
as in previous kind of conection).

Get sure that the incoming voltage for these inputs fit the appropriate range:
2..30 V.
