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+
• Unipolar-
Factory setting
None
‣
Determines which controller component the
connected actuator, e. g. the dosing pump,
should trigger.
Bipolar
"Split range"
Unipolar+
Part of the manipulated variable that the
controller uses to increase the process value
Unipolar-
For connected actuators that decrease the
controlled variable
Hold behavior Selection
• Freeze
• Fixed value
• None
Factory setting
None
Freeze
The device freezes the last value.
Fixed value
You define a fixed current value that is
transmitted at the output.
None
A hold does not affect this output.
Hold value
Hold behavior = Fixed value
