LED multi channels Gas Detector Controller MODBUS Rs 485/4-20mA
Description:
This product is a single-channel / dual-channel / four-way (4-20) mA / RS485 transmitter signal input intelligent control system developed by the company. This product is highly stable. High accuracy and high intelligence, the external control port is rich, the user can freely choose the type of the connected transmitter and the access port, and can perform on-site detection and alarm by simple setting. The system has integrated sound and light alarms and provides a relay normally open control terminal.
The system is widely used in applications where toxic and harmful
gases need to be detected. When the index of a certain gas to be
tested in the field exceeds or falls below the set standard, the
system will perform a series of alarm actions, such as alarm,
exhaust, tripping, etc.
The gas control panel can connect 1 or more detecting probes.It can monitor toxic and harmful gas content in one or more place.
