Schneider Electric LU9GC3 Communication Module

LU9GC3 is Schneider Electric’s TeSys U Modbus communication module, described as a Modbus hub or distribution module for TeSys Ultra devices. The unit carries ten RJ45 ports plus one screw-terminal block, providing a turnkey way to fan Modbus connections out from a single TeSys U installation. Catalogued as LU9GC3, this Modbus distribution module integrates with the TeSys U family to extend Modbus connectivity across multiple devices in a single panel or system. The compact block consolidates wiring for Modbus fieldbus connections, reducing cabling complexity and enabling scalable layouts where several TeSys U starters or accessories must communicate on the same Modbus network. In installations requiring Modbus supervision and control from a central PLC or SCADA system, LU9GC3 serves as the dedicated Modbus hub that coordinates communications across the TeSys U devices.
