9.1.2 Digital inputs DI
Digital input 1
NO/NC: NO Signal:
Filter alarm
Status: Off
To simplify adaptation to external functions, all digital inputs can be configured to be either
normally open, NO, or normally closed, NC.
The inputs are as standard normally open, i. e. if the input is closed, the function connected to the
input in Corrigo is activated.
Be careful when changing the input from NO to NC since some digital functions can be configured
to either NO or NC themselves. For example, you can choose if the Fire alarm input should be
activated when it is closed or opened. Therefore, there is a risk that the signal is changed twice and
the result is the opposite of the desired.
9.1.3 Universal inputs UI
On the largest hardware version, E28 there are universal inputs. These can individually be
configured as either analogue inputs or as digital inputs. When configured as analogue inputs they
can be bound to any of the analogue signals described under Analogue signals.
When configured as digital inputs they can be bound to any of the digital signals described under
Digital signals.
