|product name:||1-2CH 4-20MA alarm control host|
|Measurement object:||Various gases|
SK-6200 gas detection alarm has the characteristics of high stability, high accuracy and high intelligence. The external control ports are abundant. The user can freely choose the type and connection port of the connected sensor, and can perform field detection and alarm through simple settings. . The current version of the system has integrated alarm speakers, 2 channels of 2 channels alarm control normally open normally closed control terminal and 1 channel of all channels normally open normally closed control terminal (users can easily externally connect high power alarms or other exhaust valves and other external controls device).
SK-6200 gas detection alarm system is mainly used in situations where flammable or various toxic gases need to be detected, and the numerical indicator of the gas to be detected is displayed. When the index of a certain gas on the site does not meet the set standards, the system Will automatically perform a series of alarm actions, such as alarm, exhaust, trip, etc. (different according to different settings of the user).
Functional parameters of the machine:
1.Number of local channels: 2 channels
2.This machine can have a detector: a gas detector with an output signal of 4-20mA
3. Automatic / manual silence
4.Maximum measurement range: 9900
5.Minimum accuracy: 0.001
6, automatic inspection, automatic release alarm
7.High alarm setting range: any value (within the valid range and greater than the low alarm value)
8.Low alarm setting range: any value (within valid range)
9. Number of passive switches: two low-report passive switches and one low-report passive switch (can automatically control other related equipment. Such as: exhaust fans, high-power alarms, etc.)
System technical parameters:
1. Detection principle: The system provides 24V standard DC voltage to external sensors, collects standard 4-20mA detector input signals, analyzes and processes to complete digital display and alarm operations.
2. System and external (gas) sensor connection cable requirements: standard 3-wire connection method, single core wire diameter ≥ 1.5mm, wire length ≤ 1000m.
3． Transmitter model: SK-600.
4． Response time: ≤10 seconds.
5. Working voltage: AC 220V, 50Hz
6. Operating environment: Temperature: -10 ° C-50 ° C, relative humidity <95%
7. System power: This system has a maximum power consumption of 50W under the condition of 8 channels full load.
8. Current output: This system provides a current output port that re-outputs the sensor's input signal. (Optional function)
9. Dimensions: Length × Width × Thickness (cm): 45 × 25 × 13.
10． Applicable object: This system supports the input signal of each standard detector. Such as gas sensors: carbon monoxide, hydrogen sulfide, hydrogen, sulfur dioxide, ammonia, oxygen, chlorine, combustible gas and other gas detectors.
1-2 way 4-20MA host application:
Petroleum and petrochemical, chemical industry, smelting plant, steel plant, mining plant, thermal power plant, pharmaceutical production workshop, environmental monitoring, fire alarm, sewage treatment, gas station monitoring, security inspection, inspection and quarantine, etc. It is mainly used to monitor indoor and outdoor gas leakage. When there is a monitoring gas leak, the detector will detect the leakage information and display the concentration of the leaked body in real time, and transmit the relevant data to the controller in time. When the concentration is reached, the controller It will remind the user that a gas leak has been detected, and the associated equipment and related personnel take relevant measures, which are important instruments to ensure the safety of the environment, production, and life and property.
