Example: Principle circuit on I/O 1 (connection 1).
I/O 1 as 'input'
The input can be triggered with a potential-free,
external switching contact. In such cases, the
corresponding input is switched to GND.
Depending on the programming, a permanent or
sensing contact can be connected. The activated
input can be used to program one of the station's
control functions.
I/O 1 as 'output'
Configuration as 'output' allows for the activation of
external devices (e.g. relays) with 'Vsys' voltage
should certain events arise. In such cases, the
corresponding output is switched to GND.
The output's activation condition (e.g. alarm, fault,
isolation etc.) is defined in the customer data
programming.
