Scope of application of 8 channels of intelligent flash alarm

Different channels of the intelligent flash alarm device have completely different scopes of application. Why are some flash alarm devices usable, while others are not acclimatized? Below we focus on the scope of application of the 8-channel channel. Analysis of the scope of application of the 8-channel channel It is used in conjunction with various control and detection instruments with voltage switches or non-voltage contact switches. When the parameters in the production process exceed the limit value, an audible and visual alarm signal is issued, and the alarm contact is output to cause the operator. Pay attention and take action. Intelligent flash alarm function features Eight input signals, corresponding to eight high-brightness digital tubes or light-emitting blocks to display the current status of each channel respectively Test function Started by external contact switch or panel button Muffler function Controlled by external contact switch or panel button Main technical indicators Input signal: no-voltage switch contact or voltage signal, the allowable range of voltage input is 4-24VDC Display mode: Eight 0.8-inch high-brightness digital tubes respectively display the current status of each channel Alarm output: 1 relay alarm output, the contact capacity is AC220V/3A communication output: interface mode—isolated serial two-way communication interface RS485/RS422/RS232/Modem baud rate—300～9600bps internal free setting The same, there are 16 channels, the explanation of these knowledge hope to help you.
