Function Options Info
Source of data Selection
• None
• Sensor inputs
• Binary inputs
• Controller
• Fieldbus signals
• Mathematical functions
Factory setting
None
Source, whose value should be read out as a
frequency over the binary output.
Measuring value
Source of data ≠ Controller
Selection
Depends on:
Source of data
‣
Choose the measured value which should be
output as the frequency via the binary
output.
Actuator type
Source of data = Controller
Selection
• None
• Bipolar

• Unipolar-
Factory setting
None
‣
Determines which controller component the
connected actuator, e. g. the dosing pump,
should trigger.
Bipolar
"Split range"
