AC current sensor leakage monitoring mobile energy storage available CE certification

The BA series products apply the principle of electromagnetic induction to measure the AC current in the power grid in real time. They use constant current and linear compensation technology to isolate and transform it into a standard DC signal output. DC12V or 24V safe voltage or AC/DC85-265V voltage supply can be widely used in the field of industrial automation. The BA50L residual current transformer is mainly used to detect the leakage current of the electrical system, and can grasp the situation of electrical circuits and equipment at any time to prevent accidents such as fires caused by leakage.

This agreement specifies the physical connection and communication protocol for data exchange between BA current sensors and data terminal devices, which is similar to the Modbus RTU communication protocol.

7.1 Protocol Description: The communication protocol used by the BA current sensor defines in detail the data sequence definition of address code, function code, and verification code, which are all necessary contents for specific data exchange. This protocol uses a master-slave responsive connection (half duplex) on a single communication line, which means that signals are transmitted in opposite directions on a separate communication line. Firstly, the signal from the host computer is addressed to a terminal device (slave), and then the response signal sent by the terminal device is transmitted to the host in the opposite direction. This agreement only allows communication between hosts (PCs, PLCs, etc.) and terminal devices, and does not allow data exchange between independent terminal devices. This way, each terminal device will not occupy the communication line during their initialization and respond to query signals arriving at the local machine.
