High quality and cheap flash alarm
2012-1-10 10:10:38

全部采用集成电路设计制造,配以高亮度LED发光管,具有结构简单、性能可靠、使用方便、使用寿命长以及功耗低、体积小等优点。 All flash alarms are designed and manufactured with integrated circuits and equipped with high-brightness LED light-emitting tubes. They have the advantages of simple structure, reliable performance, convenient use, long service life, low power consumption, and small size.


This instrument is generally installed on the instrument panel of the automatic control system, and is used in conjunction with various electrical contact alarm devices or control and monitoring instruments. When a key process point in the production process exceeds (or falls below) a given

When setting the value, an audible and visual alarm will be generated, which will cause the operator's attention and timely adjust and eliminate the fault to avoid causing a production accident. It is widely used in chemical, petroleum, electric power, metallurgy, light industry and other industrial and mining enterprises.

The instrument has eight alarm circuits, each of which can monitor a control point, which can be a normally closed or normally open contact. The two buttons on the test panel of the instrument are equivalent to the lead-out terminals on the back of the instrument.

The terminal can be used on the operation table alone or in combination, making it convenient and flexible.

特点 Flash Alarm Features


1. It can be easily assembled into a multi-loop alarm system.


2. Semiconductor flat light-emitting device, high brightness, soft color, low power consumption, parallel drive, long working life, and easy replacement of lamp screen.


3. Single-chip microcomputer technology, photoelectric isolation, built-in buzzer, strong anti-interference ability of the whole machine.


4, plug-in circuit board structure, there are a variety of output methods such as relay node output and voltage output to facilitate maintenance and operation.


5, the site can choose the normally open or normally closed input method


适用于某个控制参数越限时,相应的回路可发出声光报警信号。 The flashing alarm is suitable for when a certain control parameter exceeds the limit, and the corresponding circuit can issue an audible and visual alarm signal. It adopts high-performance single-chip control, bimetal thermometer alarm window adopts LED flat panel display

Component, which has the characteristics of chromatic softness and long-distance observation. Used in conjunction with various control and testing instruments with voltage switches or non-voltage contact switches, when the parameters in the production process exceed the limit, an audible and visual report is issued

Alarm signal and output alarm contact to draw the operator's attention. Intelligent flow totalizer and measures are adopted. It is a cost-effective instrument. It has been widely used in various industries when the process parameters exceed the limit.

Sound and light alarm
