These are the leading causes of physical damage to the module's internal circuitry. Repair vs. Replacement
The B3 tier indicates a configuration featuring more integrated hardware relays and standard physical fuses than its scaled-down counterparts, the B2 or L01 modules. 2. Core Components of the Schematic Layout
: This consists of solid-state and mechanical micro-relays soldered permanently onto the PCB. Unlike traditional fuse boxes where relays can be easily pulled out, the Siemens BSM B3 features integrated relays that require precise desoldering to fix.
