Control electronics for an agricultural or forestry vehicle

Control electronics for an agricultural or forestry vehicle or an agricultural or forestry machine, the control electronics comprising:

• power connections at least for a first supply network and a second supply network;
• at least one network connection;
• a communication circuit configured to transmit data via the network connection and configured to be supplied via the first supply network;
• a logic circuit coupled to the communication circuit, the logic circuit comprising at least one control output for controlling an electrical load supplied via the second supply network, the logic circuit being connected to the second supply network via an internal supply line and an internal ground line, the logic circuit configured to be electrically supplied via the second supply network;
• and
• an isolating switch arranged in the internal supply line or the internal ground line of the logic circuit and configured to interrupt the respective internal supply line or internal ground line of the logic circuit if the second supply network is interrupted,
• wherein at least one first bridging element is connected to the first supply network and to the second supply network and is configured to at least temporarily connect the two supply networks, the first bridging element being substantially electrically insulating in an off state and being substantially electrically conductive in an on state, the two supply networks having at least a stipulated minimum isolation impedance in the off state of the first bridging element.
