Cabinet type gas alarm controller
• gas alarm controller is specially designed for industrial sites
• two alarm thresholds (low alarm and high alarm) can be set for any detector on the controller,
So as to realize hierarchical alarm and hierarchical control.
• channel design enables simultaneous monitoring and control of multi-channel gas detectors
• one 128 per channel × 64 dot matrix OLED liquid crystal indicator
• design of combustible gas alarm controller according to Chinese national standard gb16808-2008
• each channel of built-in memory can record 1000 alarm, fault or operation records
Main power: 220VAC (+ 10%, - 15%);
System capacity: each unit module can be connected with 2 current interface detectors;
Optional measurement units: "%lel", "ppm", "kppm", "ppb", "v/v%", "umol/mol";
Alarm level: low alarm and high alarm, and the alarm value can be set separately;
Display resolution: 1 when range ≥ 100, 0.1 when range ≤ 10, 0.01 when range ≤ 10;
Accuracy / repeatability: ≤ 1%f.s, error: ≤ 2%fs;
Operating temperature: 0~30 ℃;
Humidity range: 0 ~ 95% RH (no condensation);
Power consumption: power consumption per channel <2w;
Standby power: 2 × 12VDC 10Ah lead-acid battery, 2/3-wire 0-22ma current loop, identification signal
0-2ma: no power supply or circuit fault, 2-2.5ma: sensor fault;
Detector access mode: 3mA: calibration status; 4-20mA: concentration output within the range; > 22mA: out of range;
Overall dimensions:
800: 150W × 215H × 83D
880: 230W × 320H × 87D;
