The 6-port LMN Hub allows several LMN devices to be flexibly connected to form a bus, including 1:n topologies.
The space-saving design with a width of only 18 mm (1M) allows installation even in confined spaces. Tool-free mounting and optimized cable routing (top/bottom) allow a quick and hassle-free installation.
The integrated status LED provides information about the 12V supply on the LMN bus and thus enables easy fault detection.
In installations with many bus devices (e.g. meters) or with long cable lengths, the power supply provided by the gateway may not be sufficient for all bus devices. In these cases, the hub enables an additional power supply via one of the hub ports.

Application scenarios

LMN hubs are used to operate several LMN devices on one bus. The hub in a top-hat rail housing is space-saving: it is only one pitch unit (TE = 18mm) wide. A status LED for the 12V supply is integrated to enable an initial, quick assessment of the system.

In systems in which the measuring points are very widely distributed or a large number of meters are to be connected, the power supply integrated in the gateway is not sufficient. An additional 12 VDC supply must therefore be connected. This only requires a short cable that is plugged into a hub port and connected to a normal 12V DIN rail power supply unit.
