Modbus interface module BSCM module - Schneider Electric

Functions This module, required for connection to the network, contains the Modbus address (1 to 99) declared by the user via the two dials in front. It automatically adapts (baud rate, parity) to the Modbus network in which it is installed. It is equipped with a lock-out switch to enable or disable operations involving writing to Micrologic, i.e. reset, counter reset, setting modifications, device opening and closing commands, etc. There is a built-in test function to check the connections of the Modbus interface module with the Micrologic and FDM121 display unit. Mounting The module is mounted on a DIN rail. A number of modules may be clipped one next to the other. For this, a stacking accessory is available for fast clipconnection of both the Modbus link and the 24 V DC supply. The Modbus interface module supplies 24 V DC to the corresponding Micrologic, FDM121 display and BSCM module. Module consumption is 60 mA / 24 V DC.

Status indications Indication of device status: O/F, SD and SDE. Maintenance indicators The BSCM module manages the following indicators: b mechanical operation counter b electrical operation counter b history of status indications. It is possible to assign an alarm to the operation counters. Controls The module can be used to carry out communicating remote control operations: (open, close and reset) in different modes (manual, auto). Mounting The BSCM module can be installed on all Compact NSX circuit breakers and switch-disconnectors. It simply clips into the auxiliary contact slots. It occupies the slots of one O/F contact and one SDE contact. The BSCM is supplied with 24 V DC power automatically via the NSX cord when the communication system is installed.
