This type of temperature and humidity transmitter is a RS-485 bus type temperature and humidity transmitter, which uses RS485 interface, can realize multi-point simultaneous monitoring, networking and remote transmission, and has on-site digital display function. It is suitable for dynamic loop monitoring and matching, computer rooms, libraries, archives, communication base stations, medical warehousing, rail transit, distribution stations, HVAC and other scenarios.
FUNCTIONAL FEATURES
• Communication method:
This product uses the RS485/RS232 (can be ordered) interface method, and uses the MODBUS data communication protocol widely used in the industrial field for data communication, which can be directly connected to various control equipment, display instruments and computers.
• Remote transmission function:
Using the RS485 interface, the maximum transmission distance can reach 1200 meters. It can realize the remote monitoring and control of temperature and humidity.
Networking function: Multiple transmitters are connected in serial through the bus, and each transmitter needs to be powered separately by an external power supply. The bus endpoint is connected to the computer serial port through a digital signal converter. It can realize multi-point monitoring with the receiving device as the center, in order to achieve centralized control and management on a large scale. Up to 32 monitoring points can be monitored in the same network.
• On-site display:
The temperature and humidity transducer also has the function of on-site display, and the on-site temperature and humidity
changes can be directly observed through the display panel.
