1.1 Function and configuration
VEGATRENN 544 Ex Ex-separator powers via an
intrinsically safe circuit the respectively connected
sensor and processes in addition the measured data
of the sensor.
Function
The measured data of 4 ... 20 mA directly adjusted on
the sensor are processed in VEGATRENN 544 Ex into
a current and volt output as well as in a digital signal
output (DISBUS).
VEGATRENN 544 Ex is equipped with sockets for
connection of a VEGACONNECT connection cable. A
communication to a PC can be provided via
VEGACONNECT.
If necessary this combination enables in a very simple
way a parameter adjustment of the processing or
outputs or editing of linearization curves.

Configuration
VEGATRENN 544 Ex is mechanically designed in 19"-
technology (width 5 TE = 24,5 mm).
Electronically the instrument is microcomputer control-
led and consists function technically out of software
components, see following sketch.
