3. Brief description

SINEAX DME 401

is a programmable transducer with a

RS 485 bus interface (MODBUS

)

. It supervises several

variables of an electrical power system

simultaneously

The

RS 485

interface enables the user to determine the

number of variables to be supervised (up to the maximum
available). The levels of all internal counters that have been
configured (max. 4) can also viewed. Provision is made for
programming the SINEAX DME 401 via the bus. A standard
EIA 485 interface can be used.
The 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. This interface is needed for bus
operation to configure the device address, the Baud rate and
possibly increasing the telegram waiting time (if the master is
too slow) defined in the MODBUS

protocol.

The usual methods of connection, the types of measured
variables, their ratings and the type of internal power metering
are the main parameters that can be programmed.
The ancillary functions include a power system check,
provision for displaying the measured variable on a PC
monitor and a facility 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
“7.1 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. 5).
