Relative humidity and temperature transmitter DB4385

duct-mountfor integrationRS-485

This temperature and humidity transmitter is an integrated duct type temperature and humidity transmitter with an RS485 interface, which can realize multi-point simultaneous monitoring, networking and remote transmission. It is suitable for HVAC, drying, grain storage, return air duct and other application scenarios. FUNCTIONAL FEATURES • Communication method: This product adopts RS485 interface and uses MODBUS data communication protocol, which is widely used in the industrial field, for data communication. It can be directly connected to various control devices, display instruments and computers. • Remote transmission function: Using the RS485 interface, the maximum transmission distance can reach 1200 meters, which enables the remote monitoring and control of temperature and humidity. • Networking function: This temperature and humidity transmitter is connected in serial through the bus, and each transmitter requires an external power supply for separate power supply. The bus endpoint is connected to the computer serial port through a digital signal converter. It can achieve multi-point monitoring with the receiving device as the center, so as to realize centralized control and management in a large area. Up to 32 monitoring points can be monitored in the same network.
