switching output, timer functions
as output, damping function as
well as NC / NO function.
Communicative:
Process values, parameter setting
data and diagnostic information
can be transmitted via IO-Link.
Easy:
Parameter setting via IO-Link
before installation, as an alter-
native also via pushbuttons on
the sensor.
Repeatable:
Simple parameter setting of
many sensors via “copy & paste”
in the LINERRECORDER SENSOR
software or via a memory plug.
