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.
