3. Brief Description

The DMT-1024 and DMT-1042 multi-function transducers
simultaneously measure several variables of an electric
power system and process them to produce 2 or 4 analog
output signals respectively.
2 or 4 pulse outputs are available for signalling limits or energy
metering. For two of the limit outputs up to three measurands
can be logically combined.
The multi-transducers are also equipped with an RS 232 serial
interface to which a PC with the corresponding software can
be connected for programming or accessing and executing
useful ancillary functions.
The usual modes of connection, the types of measured
variables, their ratings, the transfer characteristic for
each output etc. are the main parameters that have to be
programmed.
Ancillary functions include a power system check, provision
for displaying the measured variable on a PC monitor, the
simulation of the outputs for test purposes and a method
for printing nameplates.
4. Physical Installation
The transducer can be mounted either on a top-hat rail or
directly onto a wall or mounting surface.
Note "Environmental Conditions" in Section
"6.1 Technical Data" when determining the place
of installation!

4.1 Mounting on Top-Hat Rails

Simply clip the device onto the top-hat rail (EN 50 022) (see
Fig. 4).
