YA-K300 4-Channel Gas Detector Controller with 4.3-inch LCD Display, 8 Relay Outputs, and 1200m Communication Range
The YA-K300 series gas alarm controller works with YA-D series gas detectors to create comprehensive industrial gas monitoring systems. Designed specifically for industrial environments, this system provides reliable gas detection and early warning capabilities with a 4.3-inch industrial LCD display for clear concentration monitoring.
- 4.3-inch industrial LCD display with clear gas concentration monitoring
- Audible and visual alarms when gas concentrations exceed preset levels
- Multiple output relays (2 common + 8 programmable) for driving exhaust fans, solenoid valves, and other equipment
- Supports multiple units: %LEL, PPM, mg/m³, ug/m³, %VOL
- 4-20mA and RS485 communication modes for flexible integration
- Multiple event delay confirmation to prevent false alarms
- Real-time monitoring with over 2000 data records storage
- System fault detection with acoustic and optical alarms
