Flash alarm
Adopting an internal buzzer sound system and panel indicator flashing, as well as a passive contact output from the rear terminal, to achieve a three state alarm
Overview of Flash Alarm Devices
Introduction
The intelligent flash alarm is composed of a small microcomputer detection system using the ATC51 series microcontroller, which replaces the traditional circuit that only uses hardware to implement alarm functions. This greatly reduces the number of components in the entire machine and improves reliability. The input circuit adopts a photoelectric isolator, which enables complete isolation between the CPU and external circuits. The multiple inputs are all normally open passive input methods. The alarm adopts an internal buzzer sound system, panel indicator flashing, and rear terminal output passive contact method to achieve a three state alarm. This series of instruments adopts a door entry without any components, with a reasonable structural design, superior performance, reliable operation, long service life, and easy maintenance, and is deeply trusted by a large number of users.
Scope of Application
The flashing signal alarm is suitable for when a certain control parameter is exceeded, the corresponding circuit can emit an audible and visual alarm signal. It adopts high-performance microcontroller control, and the alarm window adopts LED flat panel display components. It has the characteristics of soft chromaticity and long-distance observation. When used in conjunction with various control and detection instruments with voltage switches or no voltage contact switches, it emits sound and light alarm signals and outputs alarm contacts when the parameters in the production process exceed the limit values, to attract the attention of operators and take measures. It is a cost-effective instrument that has been widely used in various industries for sound and light alarms when the process parameters exceed the limit.
