Binary outputs
All the inputs are assigned for float switches and pressure switches
Hardware options, such as the "DIO" module with 2 digital inputs and 2 digital outputs or
fieldbus module "485" enable the following:
Via a digital output signal
– diagnostic states, point level switches, or similar states transmitted statically (similar to
a relay)
– the dynamic transmission (comparable to a non-wearing "analog output") of PFM
signals, e.g. to control dosing pumps
