SCA Ethernet M-Bus
The Ethernet adapter is used for communication over Ethernet networks.
The data is communicated using M-Bus over UDP or TCP. The adapter also has built in web
server. The web server can be accessed through a standard web browser in a PC using the IP
address of the adapter.
The Ethernet adapter is powered by 100 – 240 VAC (-20/+15%) between terminal 1 and 4. To
connect to an Ethernet network a RJ-45 connector is used.
SCA GSM/GPRS M-Bus
The GSM/GPRS communication adapter is a quad band GSM/GPRS device, which enables
communication with GSM or GPRS over GSM 850/900 and GSM 1800/1900 networks. The
ABB GSM/GPRS communication adapter support remote configuration using Short Message
Service (SMS), which provides flexible configuration of the adapter. It is also possible to read
essential meter data via SMS commands.
The adapter is powered with 100-240 VAC (-15/+10%).
SCA M-Bus extender
The M-Bus extender makes it possible to expand your SCA with up to 32 extra M-Bus units.
The M-Bus extender features standard M-Bus over IR communication and is equipped with
the unique IR-Pass Through function, making the product series stackable.The M-Bus exten-
der is only for use with M-Bus networks using M-Bus addressing.
SCA/KNX interface module
The SCA/KNX interface module is used to connect the meter to an EIB/KNX installation. The
KNX module converts the M-Bus telegrams to KNX variables. Some M-Bus data is not avai-
lable through this adapter.
