Circuit module for decoupling on-board electrical system from safety-relevant sub-circuit has emergency battery and/or decoupling circuit removably mounted in circuit module

摘要

The module (3) has a decoupling circuit (6) to regulate the voltage from the on-board circuit (2) to the safety-relevant sub-circuit (4,5). It has an associated emergency battery (7) for supplying energy to the sub-circuits. The circuit output is controlled by a processor (8) monitoring the voltage supply, whereby the emergency battery and/or the decoupling circuit is removably mounted in the circuit module.
