3.2
Principle of operation
VEGATRENN 141 is an [Ex 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.
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.
3.3
Adjustment
No adjustment or configuration of VEGATRENN 141 is necessary. A
parameter adjustment of the connected sensors can be carried out
via the HART communication sockets behind the hinged front cover.
