BH-50 is a single-channel/two-channel, four-channel (4-20) mA/RS485 transmitter signal input intelligent control system developedby Henan Bosean Electric Technology CO.Ltd. The product with high stability, high accuracy and high intelligence.The external control port is rich, users can freely choose the type of plug-in transmitter and access port,and On-site inspection and alarm can be performed with simple settings. The system has integrated sound and light alarms,provides a relay normally open control terminal. The system is widely used in applications where toxic gases need to be detected.When the indicator of a certain gas to be tested in the fied exceeds or falls below the set standard,the system will perform a series of alarm actions, such as alarm, exhaust, tripping, etc.
