VOC Toxic Gas Leakage Monitoring System Alarm Spray Booth Pid Sensor

The YA-K210 gas alarm controller is a versatile product that can be compatible with our YA-D series gas detectors, combining to form an innovative and intelligent industrial gas control system. This industrial gas early warning system is explicitly designed for use in industrial environments, providing quick and accurate gas detection results to keep your workplace, people, and valuable assets safe.

The controller is equipped with a 7-inch industrial LCD screen that displays the concentration value of all the connected gas detectors. With branch line (4-20mA) or bus (485 bus) connections, up to 256 detectors can be connected to the controller. The controller also features low limit, high limit, fault, and shielding alarm functions. When an alarm is triggered, the controller sends an audible and visual signal to indicate the alarm location and records the alarm time automatically.

Each gas detector can set up two sets of output relays, which automatically drive connected equipment, including exhaust fans and solenoid valves. Besides, the recorded alarm information can be exported through a U disk for additional analysis and record-keeping. With two PC interfaces, the data can be conveniently queried and analyzed using a host computer.

The product is designed following national standards and is extensively tested to provide excellent performance, fast response, low failure rate, and easy maintenance. The system uses a wall-mounted installation and the detector's cooperation with the controller CPU to upload and process gas detector data, complete data display, and output control functions for optimal workplace safety.

The D400 Gas Detector is an efficient and reliable gas detector with the following features:

• Displays the concentration of the detected gas.
• Fault alarm, high and low alarm.
• Field screen display, including backlight, the word is larger and clearer, and the backlight turns red when the device alarms.
• Infrared remote control input, no open cover operation, more convenient.
• Support three different sound and light output, corresponding to fault, low report, high report.
• Zero, calibrate, test function.
• Output DC4-20mA standard signal.
• Support RS485, two buses, LoRa, flexible communication mode.
• High performance ARM microprocessor for easy operation.
• Three relay (250V 5A) output, automatically open the fan and solenoid valve.
• Can store 40 high and low alarm records.
• Toxic gas detector can achieve mg/m³ and μmol/mol conversion.

1. YA-K210 gas alarm controller host embedded microprocessor, with detector signal sampling, data real-time calculation, system fault detection, power management, key scanning, display driver, alarm display, fault display, shield display, data storage, data export, 4G networking, alarm peripheral driver and other functions;

2. Intelligent system: μmol/mol and mg/m³ units can be switched;

3. 2 groups of common relays, 6 groups of programmable relays passive output, if necessary, can also be connected to the external relay linkage module;

4. Support 4-20mA, RS485, LoRa, 4G, PC and other mainstream communication methods;

5. Real-time monitoring of the measured gas concentration in the detection area, when the gas concentration reaches or exceeds the set alarm value, the controller sends the corresponding acoustic and optical alarm signals;

6. When the preset logic relationship is satisfied, the connected external device can act on its own;

7. External devices can be started directly through the controller;

8. Record separation, fault, alarm, automatic screening and separation of system records, the total number of stored records up to 2000, can be connected to the controller through the U disk export data;

9. The power supply uses 220V 50Hz AC, and the backup power uses two 12V/9Ah batteries.
