Signal type Options
• Static signal
• PFM
Factory setting
Static signal
Select the signal type.
Static signal
Comparable to a relay: output of a diagnostic status or a
limit contactor
PFM
You can output a measured value, e.g. the chlorine value
or the manipulated variable of a controller.
It functions as a "wear-free" switching contact that can be
used to activate a dosing pump, for example.
Signal type= "PFM"
Max. frequency 1.00 to 1000.00 Hz
Factory setting
1000.00 Hz
Maximum frequency of the PFM output signal
Is to equal the maximum possible upper limit of the
measuring range.
Meas. value format Options
• #
• #.#
• #.##
• #.###
Factory setting
#.##
Specify the number of decimal places.
Source of data Options
• 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 = an input
Selection dependent on
"Source of data"
"Inputs" = everything except controllers
Actuator type
Source of data = a controller
Options
• None
• Bipolar
• U
• Unipolar-
Factory setting
None
Determines which controller component the connected
actuator, e.g. the dosing pump, should trigger.
U
Part of the manipulated variable that the controller uses
to increase the process value
Unipolar-
For connected actuators that decrease the controlled
variable
Bipolar
