Typically 10k Ohm or 1k Ohm Platinum/Nickel sensors. Wiring requires a two-wire connection to the input terminal and the shared sensor common.
Controls power to the fuel pump. A failed relay here is a very common cause of no-start conditions.
The BSM B3 operates at high voltage (600V+ DC link). Unlike PLC logic troubleshooting, drive repair is dangerous and complex. The schematic provides: siemens bsm b3 schematic

Integrated MOSFET switches control external power relays, warning lights, or contactors. 3. Typical Pinout and Interface Wiring
The BSM also manages some exterior lighting and wipers. Using the Schematic to Diagnose: A failed relay here is a very common

Network communication relies on dedicated transceiver ICs. Depending on the exact revision of your B3 module, the schematic will feature RS-485 transceivers (such as the MAX485 or SN75176) to handle differential data packets across the automation bus. 3.
