High precision temperature and humidity transmitter - LCD display +2-way relay output +modbus RTU protocol - td200a

Product introduction

Td200a is a high-precision temperature and humidity transmitter developed by our company. The transmitter can monitor the temperature and humidity value in the environment in real time and display it dynamically through the digital tube. Rich display modes, which can be set according to site needs; The alarm range of temperature and humidity can be set, and the corresponding relay output can be driven according to the alarm event type, so as to control the field equipment.

It adopts 32-bit high-performance processor, with fast processing speed, strong anti-interference ability, modular program design and easy operation. Users can adjust the accuracy, alarm value and other parameters of the transmitter according to needs, and support local and remote settings.

It adopts RS485 communication medium, supports standard Modbus RTU communication protocol, and can form a monitoring system with PLC, DCS, industrial computer or monitoring software developed by our company. The transmitter hardware is fully designed according to industrial standards, with strong anti-interference ability and stable and reliable performance. It can operate in harsh environment for a long time.

The shell of the whole machine adopts waterproof design, which can be widely used in crop cultivation, livestock and poultry breeding, warehouse and other environmental monitoring.

Technical Parameter

Product Advantages

TD200A is a high-precision temperature and humidity transmitter independently developed by our company. This transmitter can monitor real-time environmental temperature and humidity values and dynamically display data on the LCD screen.

It supports rich display modes configurable according to site requirements; temperature and humidity alarm ranges can be set, and corresponding relay outputs can be driven according to alarm event types to control field equipment. Adopting RS485 bus output, it can be directly connected to field controllers such as PLC for data processing.

It has a wide temperature measurement range and high precision. The TD200 covers a temperature measuring range of -40℃ to 125℃ with an accuracy of ±0.3℃.

• It uses RS485 communication medium and supports the standard Modbus-RTU communication protocol, which can form a monitoring system with PLC, DCS, industrial PC or monitoring software developed by our company.

• It is equipped with a 32-bit high-performance processor featuring fast processing speed and strong anti-interference ability. Its modular program design ensures convenient and easy operation.
