Product features:

1, style optional: standby power model/no standby power model, two styles are available, standby time ≥90 minutes when the standby power model is not powered on, even if the short power failure does not affect the normal use

2, high-definition color screen: 4.3-inch industrial high-definition color screen display, strong resolution, high clarity, more convenient and intuitive data reading

3, more rich functions: embedded rich software function microprocessor, complete detector signal sampling, data real-time calculation, system fault detection, power management, key scanning, display driver, alarm display, alarm peripheral driver and other functions

4, easy to operate: YA-K300 series gas alarm controller using physical keys, marked, simple operation

5. Data storage: At least 2000+ fault and alarm records can be stored

6, to prevent false alarms: In the judgment of alarm failure, the use of multiple event delay confirmation method, effectively prevent false alarms, to provide a strong guarantee for the safety of life and property

7, upgrade and development convenience: equipment upgrade only need to increase the corresponding number of "expansion board", can be connected to any branch line system and the same protocol of the bus system detector, can be expanded from 2, 4, 6, 8 to 8 (each increase of 1 expansion board, increase 2 configuration), up to 32 detectors can be connected

8, intelligent system: YA-K300 series gas alarm controller supports %LEL, PPM, Mg/m3, ug/m3, %vol and other units

9, the output interface diversification: built-in 10 groups of relays (2 groups of public relays +8 groups of programmable relays), interface expansion is rich, can be active and passive mode to drive the exhaust fan, solenoid valve and other equipment, to adapt to different field conditions

10, the installation is simple: wall-mounted installation, through the use of the detector, and through the controller MCU to upload the data of the gas detector for a variety of data processing, and finally complete the data display, output control and other functions
