Schneider Electric LV434000 Modbus Interface Module

Schneider Electric LV434000 Enerlin'X IFM - Modbus-SL Interface for One Circuit Breaker is a Modbus-SL communication module that attaches to a single circuit breaker with a MicroLogic trip unit, enabling two-wire Modbus connectivity to a master controller. The unit uses two RJ45 ULP ports, providing 24 Vdc from the Modbus socket and requiring a second ULP connection to a line terminator, IO module, or FDM121 display unit for proper operation. Once installed, the circuit breaker is treated as a Modbus slave, exposing electrical values, alarm status, and open/close signals to a Modbus master for monitoring and remote control. It supports a wide range of Schneider Electric breaker families, including MasterPact MTZ, NT/NW; ComPacT NS; PowerPacT P- and R-frame; and NSX, making it suitable for Enerlin'X installations that need centralized data integration into PLC or SCADA systems via Modbus-SL. The IFM module also includes a built-in test function to verify the integrity of the Modbus connection to the breaker and any connected display unit, ensuring reliable remote operation of protective equipment.
