Dual analog circuit breaker

The dual channel analog circuit breaker input control terminal can input AC/DC current signals to trigger the action of the analog circuit breaker. Thus, the operating characteristics of AC/DC circuit breakers can be simulated. Greatly convenient for users. The $r $n dual analog circuit breaker can export test data to a computer through a USB drive. And it has RS-485 interface and supports Ethernet Modbus protocol communication, which can simulate the closing and opening control of circuit breakers through remote control in the background. The background can also read the position information of the simulated circuit breaker, which can be controlled and operated through the upper computer.
