Product Application Scheme
HCEAP series arc light microcomputer monitoring system is a modular system, which is mainly composed of a main control unit and an arc light acquisition unit.

HCEAP1000 main control unit
It is used for managing and controlling the whole arc light protection system. It detects the arc light signal, judges and processes the acquired signals. When the alarm conditions are met, it sends the alarm command to the high-speed relay to complete the prompt action.

Its terminals include:
Four arc light signal detection interfaces, which is mainly used for receiving the arc light fault signal from the acquisition unit.
Three data communication interfaces, in which one interface is used for data input, and other interfaces are used for data output. Four high-speed tripping output interfaces.
One main control unit can simultaneously protect several detection areas, so that the acquisition units of the arc light microcomputer monitoring system can be scattered to different locations totransmit the detected arc light signals to the main control unit.
The data transmission between the main control unit and the acquisition unit is completed through the optical fiber and the data transmission line. The optical fiber transmits the trigger signal to the main control unit. The working power supply, the alarm signal and the self-control data information flow are transmitted through the data transmission line.
