CAKJ-XHB-8X~48X Microcomputer Central Signal Alarm Device
1，OVERVIEW
CAKJ-XHB separate micro computer central signal alarm device is a centralized management device that designed for Power station and Transformer substation signal system. The device that extensively used in electric, petrochemical, chemical industry, metallurgy and coal industry, is a high intelligent product that automatic monitoring and signal alarm for power and industrial.
2，FUNCTIONAL CHARACTERISTICS
1）The panel includes digital display and power on self test (POST).Integrated design.
2）Provide with test (light test), confirm (accept), return（reset）, signal recall and clear function. With function buttons.
3）Provide with manual and automatic accept function, automatic accept time limit (0-200s) able to set.
4）Signal alarm type able to distinguish: accident signal S, warning signal Y, position signal P, all available to set.
5）Alarm window color: able to choose red, white, yellow, green, accord to signal alarm type, separated by color is more obvious and visually.
6）Input signal status: switch contact (h), switch hold contact (E), and pulse hold contact (C). (Note)
7）The input signal is normally open and normally closed. For each signal, the normally open and normally closed alarm (default) can be set, and the normally closed variable normally open alarm can be set.
8）Signal delayed alarm: 0-9999ms delay alarm time limit able to set.
9）Device bring with buzzer, when accident happy it sounds “bi—”, warning signal sounds short beep “bi, bi, bi, bi”, position signal doesn’t sound.
10）Device with accident and warning signal alarm output contact, able to activate electric bell, enhance the alarm effect.
11）With remote signal output contacts, connect to other devices or as an accident stop signal.
12）It has the device power disappearance contact output.
13）Provide with digital communication output, RS485 serial communication contact, MODBUS communication protocol.
◆Note: Explanation of input signal status and alarm procedures
When“h” is selected as the input signal state (default), the workflow is as follows:
