Signal Collection Module

The Signal Collection Module adopts the AVR single-chip microcomputer system, which collects the input switching signal through photoelectric isolation, and finally uploads the received status and alarm switching input information to the monitoring device through the RS485 bus for data analysis and processing. The function of the Signal Collection Module is to collect and upload the status and alarm signals of each power distribution part in the power system.

The FKR-21 Signal Collection Module adopts the three-terminal isolation conversion method of input, communication, and power supply to pick up the status and alarm signals of each power distribution component in the power system. Meanwhile, it has the function of RS485 serial port communication, so as to conveniently realize the uploading of monitoring data of each switching signal in the power system.
