Tips: Main functions of current collectors

• Current measurement and acquisition: The main function of the current collector is to collect current signals through sensors or transformers and measure the current value of the device. The collected signal can reflect the load status, working health and other information of the device.
• Signal conversion and output: The current signal collector usually converts the measured analog current signal into a standardized output signal for subsequent analysis, control or remote monitoring.
• Remote monitoring and communication: Many modern current collectors support remote monitoring functions, and transmit the collected current data to the control system through communication protocols to achieve centralized management and real-time monitoring.
• Alarm and data recording: The device usually has a fault alarm function. For example, when the current exceeds the limit, short circuit, overload, etc., an alarm will be triggered to remind the user to deal with it in time. Some current collectors also support historical data recording, which is convenient for data analysis and troubleshooting.
