3.2 Principle of operation

Application area
VEGATRENN 149A Ex is an [EEx ia] separator
with separate power supply for connection of
4 ... 20 mA/HART sensors in two-wire version. As
an associated electrical device, it ensures a
galvanic separation between sensor circuit and
processing circuit and thus between Ex and non-Ex
areas.
Functional principle
An integrated transmitter power supply powers the
connected sensor. The current signal from the
sensor (4 ... 20 mA) is transferred linearly and
galvanically separated to the output. The HART
communication sockets in the front enable a
bidirectional transmission of HART signals.
Voltage supply
Wide-range power supply unit with 20 ... 253 V AC/
DC for world-wide use.
