Examples which show how the inputs can be connected
Example 1 - Potential-free contact
A: Potential-free contact
B: Device with an output
C: Communication module
Between INx and GND a potential-free contact is connected (e.g.
a switch or a relay). As soon as the contact closes, INx is con-
sidered to be ‘active’.
Example 2 - Open-collector output
A: Open-collector output
B: Device with an output
C: Communication module
A device with an open-collector output is connected to INx of the
communication module. As soon as the output is activated, INx is
considered to be ‘active’.
