Supply voltage
5 to 30 V DC
(Control circuit to DIN 19234/NAMUR)
Switching state logical
‘0’: current > 0.35 mA to < 1.2 mA
‘1’: Current > 2,1 mA
Direction of action
standard logical ‘0’ or logical ‘1’
(configurable)
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).

technology
24 V DC (10 to 30 V DC)
Characteristic curve
rising or falling (configurable)
Deviation
< 1 %
Module for digital feedback
SW1, SW2*
Two switches for binary position feedback (position adjustable
within the range of 0 to 100 %, ranges cannot overlap)

Supply voltage
5 to 11 V DC
(Control circuit to DIN 19234/NAMUR)
Signal current
< 1,2 mA: Switching state logical ‘0’
> 2,1 mA: Switching state logical ‘1’
Direction of action
standard logical ‘0’ or logical ‘1’ (configurable)
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.
