1.Central Processing Unit (CPU): Functions as the "brain" of the system host, responsible for processing and analyzing all data received from field protectors, and making judgments and responses based on preset logic.
2.Communication Unit: Responsible for data exchange with on-site current-limiting protectors. Common communication methods include RS485 bus, following protocols such as Modbus-RTU.
3.Display Unit: Used to intuitively display system operation status, real-time data, alarm information, and historical records, facilitating viewing and operation by management personnel.
4.Alarm Unit: When abnormalities are detected, it issues alerts through audible and visual means to draw management personnel's attention.
