Description:
  • The bus module is the base for all X20 supply modules
  • For creating voltage groups
  • The internal I/O supply is isolated to the left
  • Manual node number assignment
  • Independent of electronics module
  • Manual and automatic addressing can be combined as desired

The BM05 bus module is the base for all X20 supply modules. This bus module is also used to determine a unique address using node number switches.
