Single/double/four (4-20) mA/RS485 transmitter signal input intelligent controllable system, the product has high stability. High accuracy and high intelligence, rich external control ports, users can freely choose the type of transmitter and access port, and can perform on-site detection and alarm through simple settings. The system has integrated sound and light alarm, and provides relay normally open control terminal.
The system is widely used in occasions where poisonous and harmful gases need to be detected. When the index of a certain gas to be detected on site exceeds or falls below the set standard, the system will perform a series of alarm actions, such as alarm, exhaust, trip, etc.
Detection principle: Collect standard 4~20mA signal input or RS485 communication input (optional), analyze and process to display the current gas concentration of each channel, and operate related alarm signals, and can also transmit information to the computer through RS485 bus.
Applicable objects: The system supports the input signals of various standard Detectors, such as Gas Detectors: carbon monoxide, hydrogen sulfide, sulfur dioxide, hydrogen, ammonia, oxygen, chlorine and combustible gases, etc.
