Schneider - LV434000 MODBUS SL INTERFACE ENERLIN'X IFM - FOR ONE CIRCUIT BREAKER, 24VDC, 3A

LV43400 MODBUS Communication Interface for Enerlin?X Circuit Breakers

The LV434000 Modbus communication interface is required for connecting the MasterPact MTZ, NT/ NW or ComPact NS and NSX series circuit breakers to a Modbus network whenever the circuit breaker has an ULP port (Universal Logic Plug). The port is available on BCM ULP breaker module for the MasterPact range and BSCM module for the ComPact range. Please not that the IFM is defined as an IMU (Intelligent Modular Unit) within the ULP connection System documentation.

Once the IFM has been connected to a circuit breaker, the circuit breaker is considered as a slave by the Modbus master. Its electrical values, alarm status, open/close signals can be monitored or controlled by a Programmable Logic Controller or any other system.

Communication Interface Features:

ULP port

• 2 RJ45 sockets, internal parallel wiring
• Connection of a single circuit breaker
• An ULP line terminator must be connected to the second RJ45 ULP socket
• The RJ45 sockets deliver a 24 V DC supply fed from the Modbus socket. Built-in test function, for checking the correct connection to the circuit breaker

Modbus slave port

• Modbus Serial RJ45 port - RJ45 connector provides fast and reliable wiring
• Lateral socket, for DIN rail stackable connector
• Both top and lateral sockets are internally parallel wired.
• Multiple IFM can be stacked, thus sharing a common power supply and Modbus line without individual wiring

On the front face:

• Modbus address setting (1 to 99): 2 coded rotary switches
• Modbus locking pad: enables or disable the circuit breaker remote control and modification of IFM parameters
• Self-adjusting communication format (Baud rate, parity)

24 V DC power supply

• Screw clamp terminal block
• High electrical insulation between Modbus and 24 V DC connectors
• Separated lines provide improved communication robustness
