ADDTRON LM-FH5FM Ethernet Hub 16 Port PLC II3

ADDTRON LM-FH5FM is a 16-port Ethernet hub from ADDTRON designed for PLC-related networking tasks. It provides 16 RJ-45 ports to connect multiple Ethernet-enabled devices—such as PLC controllers, operator terminals, and sensors—on a single LAN segment, enabling straightforward data sharing and control signaling across the network. As a hub, the LM-FH5FM forwards incoming packets to all other connected ports, reflecting its non-switching, non-segmented topology and making it suitable for compact control cabinet deployments or lab setups where simple, unmanaged connectivity is sufficient. Typical installations place the LM-FH5FM in an equipment cabinet or on a workbench, serving as a straightforward Ethernet backbone to link PLCs, sensors, and I/O devices in a compact topology. Because it is a hub, it does not provide traffic management features such as VLANs or QoS, so network designers should ensure that devices tolerate shared bandwidth and potential collisions in small, non-segmented networks. The LM-FH5FM model name identifies this specific unit within ADDTRON’s hub lineup, distinguishing it from switches or routers and signaling a basic, plug‑and‑play Ethernet backbone for industrial environments where ease of cabling and minimal configuration are valued.
