BA series output 4-20mA or 0-5v intelligent current sensor

The intelligent BA series current sensor uses the principle of electromagnetic induction to measure the AC current in the power grid in real time and uses constant current and linear compensation technology to isolate and transform it into a standard DC signal output, or through the RS485 interface (Modbus-RTU protocol) to transmit the measurement data. DC24V or 12V safety voltage power supply, can be widely used in the field of industrial automation. BA50L(Ⅱ)-AI is an AC residual current transformer, which mainly detects the leakage current of the electrical system, can grasp the status of electrical circuits and equipment at any time, and prevent fires and other accidents caused by leakage.
