Figure 12-10 Digital outputs: signal processing using DO 0 of TB30 as an example
Properties
● Separate power supply for the digital outputs.
● Source of output signal can be selected by parameter.
● Signal can be inverted by parameter.
● Status of output signal can be displayed
– as a binector output
– as a connector output
Note
Before the digital outputs can function, their own electronics power supply must be
connected.
