Digital outputs
Signal processing using the digital outputs is shown in the function diagrams listed below.
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
Note
Before the digital outputs can function, their own electronics power supply must be
connected.
