Option modules

Module for analog feedback AO*

Without any signal from the positioner (e.g. 'no power' or
'initializing') the module sets the output to > 20 mA (alarm level).

Module for universal input UAI*

Module for a 4 to 20 mA input for universal use.
The range can be scaled. It is used for advanced valve
diagnostics. For example, an ultrasonic sensor can be connected
to detect a faulty valve seat or a phonometer can be connected
to detect cavitation.
The limit values for detecting up-scaling can be freely selected.
