Fact Sheet

SonoRepeat 111™
M-Bus repeater for Smart Metering

SonoRepeat 111 is a M-Bus repeater
there together with SonoCollect 111
is a product family there addresses
huge meter installations. The perfor­mance of the M-Bus interface and the
CPU is very high.

Larger networks and longer distances
can be covered and a higher number
of meters can be connected to the
M-Bus. SonoRepeat 111 combines
a slave interface to the logical bus
master on the one side and an own
master interface to the slaves or
meters on the other side.

The data is transparently transmitted in both directions. As the
repeater powers its subnet, the physical load of the logical master
is clearly reduced.

Complete functionality

SonoRepeat 111 supports up to 500 Unit Loads at the wired M-Bus
interface directly.

Status LEDs signaling TX, RX and collisions on the M-Bus. M-Bus
is short circuit protected (self-resetting fuse), and M-Bus slave
and M-Bus master are galvanically isolated. SonoCollect 111™ and
SonoRepeat 111 is a consolidated device which Fulfills all duties
and responsibilities of Smart Metering. Real Plug’n’Play saves time
and effort.
