Output
For use as an output pin, Pin 26 or Pin 15 is connected to Ground
through a circuitry transistor (for example Pin 24 for X3, Pin 19
for X6), if the program sets the Pin to a logical „1“.
If the program sets the pin to logic „0“, then the transistor is
disabled and thus, there is no connection between pin 26 or Pin 15
and Ground.
In order to use the output, an external power supply, in the range of
5 V and 28 V, is required. It is also possible to use the power
supply pin (pin 25 of X3) for power supply.
Figure 3 and Figure 4 depict two possible connections.
a)Connection from the Grabbers‘ power supply pin
b) Connection from external DC voltage supply source
