Category: I/O systems > X20 System > Bus modules
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.
