3.2
Principle of operation
VEGATRENN 151 is an [EEx ia] separator for connection of
4 ... 20 mA/HART sensors in two-wire version. A separate power sup-
ply 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 151 is
suitable for bidirectional transmission of HART signals. The HART
signal can be tapped via the front-mounted HART communication
sockets or the terminals.
3.3
Adjustment
No adjustment or configuration of VEGATRENN 151 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
