Industrial Wall Mounted LCD Temperature and Humidity Transmitter RS485 Output


Introduction to ZONEWU RS485 LCD Temperature and Humidity Transmitter:

Industrial grade wall mounted LCD temperature and humidity transmitter, designed for long-term monitoring in harsh environments. It adopts industrial grade microprocessor chips imported from the United States and high-precision temperature and humidity sensors, with excellent reliability, anti-interference ability, and interchangeability. The product supports 10-30V wide voltage power supply, with a maximum power consumption of only 0.4W. It can output RS485 (ModBus RTU protocol, communication distance of 2000 meters) or 4-20mA/0-10V analog signals, making it easy to connect to PLCs, industrial computers, and various IoT systems. The high-definition LCD screen displays real-time temperature and humidity values as well as device addresses. With three physical buttons, it can complete parameter settings such as address, baud rate, and calibration values, and can be debugged without the need for an upper computer. High protection level, supports wall mounted and 35mm standard rail installation, suitable for industrial and commercial scenarios such as computer rooms, warehouses, workshops, distribution rooms, greenhouses, etc.


Core Advantage:

  • Accurate and stable: humidity accuracy ± 2% RH (@ 25 ℃, 60% RH), temperature accuracy ± 0.4 ℃ (@ 25 ℃); Long term drift ≤ 1% RH/year, ≤ 0.1 ℃/year, response time humidity ≤ 25s, temperature ≤ 8s (1m/s wind speed).
  • Flexible communication: Standard ModBus RTU protocol, adjustable address (1-254) and baud rate (2400-115200); RS485 has maximum load capacity, anti-interference design, and supports multi slave unit networks.
  • Firm and easy to install: high protective shell, dust-proof and anti-aging; Backboard with sliding rail, wall mounted hole spacing of 70mm, compatible with 35mm DIN rail, flexible on-site installation.
  • Convenient operation: LCD large screen display (resolution 0.1), three key password protection (default 888), on-site modification of device address, baud rate, temperature and humidity calibration values and passwords, automatic parameter saving.
  • Wide range adaptation: probe working temperature -40 ℃~+80 ℃ (optional+120 ℃), humidity 0-100% RH; transmitter circuit -20 ℃~+60 ℃, suitable for cold and high temperature workshops in the north.
