4-20mA Communicate Gas Alarm Controller Wall Mounted YA-K210

The YA-K210 gas alarm controller can be combined with our YA-D series gas detectors to form an industrial gas intelligent control system.

The product is a gas detection and early warning system designed for industrial environment. The controller uses a 7 inch industrial LCD screen to display the concentration value of all gas detectors, the detector uses a branch line (4-20mA) or bus (485 bus) to connect with the controller, up to 256 detectors can be connected, the controller has a low limit, high limit, fault, shielding alarm function, alarm to send the corresponding alarm sound and light signal, Indicate the alarm location and record the alarm time; Each gas detector can be set up low alarm, high alarm two sets of output relays, drive the exhaust fan, solenoid valve and other equipment, alarm records can be exported through the U disk; Two groups of PC interface, through the host computer to query the data; The design follows the national standard, has the advantages of fast response, low failure rate and easy maintenance.

The product adopts wall-mounted installation, through the cooperation with the detector, and through the controller CPU 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.

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.
