3.2 Principle of operation
VEGATRENN 152 is a double channel [EEx ia] separator for connec-
tion of two 4 … 20 mA/HART sensors in two-wire version. A separate
power supply is not necessary. As an associated electrical device, it
ensures a galvanic separation between sensor circuit and processing
circuit and thus between Ex and non-Ex areas.
The current signal from the sensor (4 … 20 mA) is transferred linearly
and galvanically separated to the output. The VEGATRENN 152 is
suitable for bidirectional transmission of HART signals. The HART sig-
nal can be tapped separately for each channel via the front-mounted
HART communication sockets or the terminals.
3.3 Adjustment
No adjustment or configuration of VEGATRENN 152 is necessary. A
parameter adjustment of the connected sensors can be carried out
via the HART communication sockets behind the hinged front cover.
Adjustment of the connected sensors is carried out preferably via a
