BSCM Modbus SL/ULP Module Presentation

The BSCM Modbus SL/ULP module with commercial reference LV434220 is a Breaker Status Control Module that can be used to communicate data via:

  • Modbus Serial Line communication network

  • ULP communication network

Use the BSCM Modbus SL/ULP module with ComPacT NSX DC circuit breakers equipped with thermal-magnetic trip units, and with ComPacT NSX DC switch-disconnectors.

NOTE: The BSCM Modbus SL/ULP module cannot be installed in a ComPacT NSX DC EP circuit breaker.

The following data is exchanged:

  • OF and SDE circuit breaker states from the BSCM Modbus SL/ULP module

  • SD circuit breaker state from SD auxiliary contact for BSCM Modbus SL/ULP module or NSX cord (if present)

  • Control instructions for the communicating motor mechanism (if present): opening, closing, and resetting

  • Information to assist the operator: storage of the last 10 events

For more information about integrating ComPacT NSX DC circuit breaker communication functions, refer to:

Modbus Serial Line LED Indication on BSCM Modbus SL/ULP Module

The Modbus Serial Line LED color on the BSCM Modbus SL/ULP module is white.

The LED status is as follows:

  • Off: the Modbus Serial Line communication network is disabled.

  • On steady: the Modbus Serial Line communication network is enabled.

  • Blinking: the Modbus Serial Line communication is ongoing.

Installing the BSCM Modbus SL/ULP Module

The slots used to install the BSCM Modbus SL/ULP module depend on the circuit breaker type.
