SFD-300The type of SFD-300 gas alarm controller
(1).png){kind=small}
Advanced and high capacity of the main control chip:（ARM Cortex™-M3）Using (ARM Cortex ™ - M3) 32-bit high speed operation of industrial control,12 AD conversion chip,higher speed and precision.Only when necessary,a TF card,can be in the manufacturer's website to download the latest system program to upgrade equipment, upgrade the operation is simple.
The powerful,rich control performance：2.8 inch TFT color touch-screen,full Chinese menu operation；
Article 7500 of the start-up,shutdown and low alarm,high alarm,fault alarm record.
After has the wrong operation,the function of quick restore factory Settings.
low alarm,high alarm,beyond the range alarm,fault,main/standby switch alarm is set by different background color and sound.
Through internal alarm controller menu Settings,select display testing gas type,range and units.As long as the change set,an alarm controller can connect multiple types 4-20 mA output signal of the transmitter.
With a warning, alarm,fault three alarm switch output, and can set the alarm switch at the scene of normally open,normally closed,or the output the pulse.
Boot self-checking equipment operation condition,can the independent judgment and show the cause of the gas alarm device failure in Chinese.
