M-Bus - RS-485 slave converter
Used to adapt and galvanically separate two transmission standards
(M-Bus and RS-485). It allows direct connection of CONTECA
®
EASY
meters to an M-Bus transmission line, making them visible as slave
devices.
Electric supply: 230V (ac) - 9VA
Operating temperature: -10 – 60 °C.

Application diagram for M-Bus slave converter - RS-485 code 755058
The software protocol used for supervisor/CONTECA
®
environment
interfacing utilises the M-Bus standard (complies with EN 1434 part 3).
N.B.
:
The transmission bus, code 755855 LSC, is two-way (cross-section 2
x 1 mm
2
). The controller allows
max. 250 users
.
The
maximum length
of each individual section is
1200 m
.
It is possible to lay
up to 4 separate sections
using the MULTIPLEXER,
code 755005.
