1. Overview
The CAKJ-XXS-288E Central Signal Alarm System is a centralized management microcomputer signal alarm system designed specifically for the signal system of power plants and substations. It features strong anti-interference ability, simple operation, convenient installation and use, and low maintenance.
This alarm system adopts a distributed structure. The “alarm host” collects alarm data from the “open-in module” through the field bus, and transmits the obtained alarm signal to the “alarm window box” and “alarm sound” according to the internal setting instructions of the host, completing the sound and light alarm of the fault signal.
This product is widely used in power, petroleum, chemical, metallurgical, and coal industries, and is a highly intelligent product for power and industrial automatic monitoring and signal alarm.
System Components:
- Light Word Plate Box
- Host
- Open-in Module
- Drive Module
