For rail installation
SITRANS TR and SITRANS TW are
the universal specialists for DIN
rail installation. They provide
comprehensive diagnostic and
Two-wire SITRANS TR and Four-wire SITRANS TW
When connected directly in the 4 to
20 mA loop, the SITRANS TR devices require no
auxiliary power supply. They are installed
in junction boxes or in the control
room close to the process, thus
permitting centralized access to all
connected measurement points.
The separate auxiliary power connection
ensures the great flexibility of
the SITRANS TW devices in view of the output
signals. For example, the SITRANS TW
provides not only the most commonly
used 4 to 20 mA output signal but can
also be configured for 0 –20 mA and
0 –10 V or 2 –10 V via HART protocol.
