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
