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.

Code

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.
