Commander Series Fixed Gas Detector

The Commander series gas alarm controller is a product specifically designed for industrial sites. The YQKZ series can connect to multiple gas detectors and simultaneously display the combustible gas concentration in the areas where these detectors are located. When the combustible gas concentration in any protected area exceeds the preset alarm threshold, the controller can emit corresponding audible and visual alarm signals, indicating the alarm area and the concentration at the time of the alarm, and continue to monitor the dynamic gas concentration in the alarm area

Product Features

High-precision sampling, high safety, and high real-time performance
Modular design, high scalability Each module is powered by an independent power supply, ensuring high stability Multi-channel design enables simultaneous monitoring and control of multiple gas detectors

Product Specifications

I. Detection Performance
1. Instrument capacity: 1. A single wall-mounted unit can be equipped with 2-16 channels of 4-20mA detectors; multiple wall-mounted units in a network can be equipped with 1024 channels of 4-20mA detectors through branching 2. Single cabinet can be connected to 80 or 112 channels of 4-20mA branching detectors; multiple cabinets can be networked and equipped with 20,480 channels of branching 4-20mA detectors 2. Information Display: Each channel features a 128×64 dot matrix OLED display in Chinese (for alarm, concentration, and fault information). Additionally, each channel includes four indicator lights (low alarm, high alarm, fault, and online). Each channel has independent alarm indication, sound and light, recording and mute functions, as well as an independent self-checking feature 3. Audible Alarm: Piezoelectric ceramic speaker, two types of sounds (alarm, fault), greater than 90dB 4. Historical Records: Each channel has a built-in memory capable of recording up to 1000 alarm, fault, or operation records 5. Alarm Levels: Low and High Alarms, with alarm values individually configurable 6. Measurement unit: "%LEL"; ,” ppm” ,” kppm” ,” ppb” ,” V/V%” ,” umol/mol”
7. Resolution: 1 for ranges ≥100, 0.1 for ranges between 10 and 100, and 0.01 for ranges ≤10 8. Accuracy: 1% F.S,
9. Error: ≤2% FS II. Electrical Characteristics 1. Main power supply: 220VAC (+10%, -15%) 50Hz 2. Standby power supply: DC24V maintenance-free lead-acid battery, with battery capacity determined based on the number of detectors connected 3. Power consumption: The maximum capacity of a single wall-mounted enclosure is 16 channels, with a maximum power consumption of <100W. The power consumption varies with the number of channels. The maximum capacity of a single vertical 19-inch cabinet is 80 channels, with a maximum power consumption of <500W. The power consumption varies with the number of channels 4. 4-20mA Input/Output: Each unit features two 4-20mA inputs for connecting gas detectors, as well as two 4-20mA outputs for connecting to the superior DCS equipment. 4-20mA signal format: ・0-2mA: No power supply or circuit fault ・2-2.5mA: Sensor fault ・3mA: Calibration status ・4-20mA: Concentration output within range ・>22mA: Out-of-range 5. Each alarm output control channel: two alarm relay outputs (contact capacity 30V/1A) 6. Total fault output: There is one channel of total fault relay output (contact capacity 30V/1A) 7. Communication Interface: RS-485 communication interface (Modbus) III. Structural Characteristics 1. Installation method: Wall-mounted, cabinet-mounted 2. Dimensions: Wall-mounted GP6000: 230mm×320mm×87mm 19-inch cabinet: 1800mm×600mm×600mm / 2100mm×800mm×800mm IV. Environment
1. Operating temperature: -10℃~50℃ 2. Storage temperature: -20℃~70℃ 3. Humidity range: 0~95% RH (non-condensing)
