This is a breaker status communication module (BSCM) for ComPact NSX circuit breakers. The optional BSCM for ComPact NSX is used to acquire device status indications and control the communicating remote-control function. It includes a memory used to manage the maintenance indicators. It serves as a converter between the analog outputs of the device indication contacts (O/F, SD, SDE) and the digital communicating functions. It is needed for communication of status indications, controls and measurements. The BSCM is installed inside the circuit breaker behind the front cover. It is connected to external Ethernet or Modbus interfaces (IFE/IFM) via the NSX cord terminal block. The BSCM operational voltage is 24 VDC.
