| Zusammenfassung: | The utility model relates to a multi-loop comprehensive measurement and control device, which comprises a circuit board positioned in an outer shell, a microcontroller and a plurality of interface pieces are arranged on the circuit board, each interface piece comprises two input ports, the two ports of each interface piece are respectively connected to a communication port of the microcontroller after passing through an isolating circuit, and the microcontroller is connected with the communication port of the microcontroller after passing through the isolating circuit. And one port of the plurality of interface pieces is electrically connected together, half of the interface pieces are positively connected to the microcontroller through the two output ends of the isolating circuit, and the other half of the interface pieces are reversely connected to the microcontroller through the two output ends of the isolating circuit. The multi-loop comprehensive measurement and control device can be applied to large-cur |
