PROBLEM TO BE SOLVED: To provide an electric or electronic device to which two independent supply voltages can be supplied in operation.SOLUTION: An electric or electronic device includes: a first connection interface 70 that can be connected to a ground conductor and a voltage conductor of a first electric network, and a serial bus system 75 capable of conveying data; a second connection interface 71 that can be connected to a ground conductor and a voltage conductor of a second electric network; a control module 74 to which a first voltage value is supplied and which can receive and/or transmit data; and a switching module 76 serially inserted between the bus 75 and the control module 74. Each connection interface has a ground connection and is connected to each other to form a common ground. The switching module 76 is switched to a closed position when data is transmitted and/or received, and is switched to an open position when every input/output of the first connection interface is connected to each other. |
