SINEAX DME 401 with RS 485 Interface

Programmable Multi-Transducer

without analog outputs, transfer of data via a MODBUS®-


interface

Application
SINEAX DME 401 (Fig. 1) 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 Fig. 1. SINEAX DME 401 in housing T24,
to which a PC with the corresponding software can be connected clipped onto a top-hat rail.

functions. This interface is needed for bus operation to configure

Low-voltage system in high-voltage system

Connecting devices to the bus


The RS 485 interface of the DME 401 is galvanically isolated from
all other circuits. For an optimal data transmission the devices are
Relationship between PF, QF and LF connected via a 3-wire cable, consisting of a twisted pair cable
(for data lines) and a shield. There is no termination required. A
Output shield both prevents the coupling of external noise to the bus and
ind. cap. ind. cap. limits emissions from the bus. The shield must be connected to
solid ground.
QF You can connect up to 32 members to the bus (including master).
PF
Basically devices of different manufacturers can be connected to
the bus, if they use the standard MODBUS® protocol. Devices
without galvanically isolated bus interface are not allowed to be
connected to the shield.

The optimal topology for the bus is the daisy chain connection

from node 1 to node 2 to node n. The bus must form a single
continuous path, and the nodes in the middle of the bus must
have short stubs. Longer stubs would have a negative impact on
signal quality (reflection at the end). A star or even ring topology

There is no bus termination required due to low data rate. If you
