Principle of operation

VEGATRENN 141 is an [EEx ia] separator with separate power sup-
ply 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.
An integrated transmitter power supply powers the connected sensor.
The current signal from the sensor (4 ... 20 mA) is transferred to the
output linearly and galvanically separated. The instrument is HART
transparent, i.e. the HART signals are transmitted bidirectionally
between input and output.
Wide range power supply with a nominal voltage of 24 ... 230 V AC
50/60 Hz or 24 ... 65 V DC.
