Acrel WHD48-11 Temperature Humidity Multi Sensor By Modbus Rs485
Acrel's WHD48-11 is a modbus RS485 temperature and humidity multi-sensor with a measuring range of -40.0°C to 99.9°C for temperature and 0% to 99% RH for humidity. With precision of ±1°C and ±5%RH, its transmitting output is DC 4-20mA or DC 0-20mA. The controller's working condition has a temperature range of -20°C to +60°C and humidity of ≤95%RH, without condensation and corrosive gas. Suitable for humidity control, heating for temperature rising, and blowing for temperature decreasing, it has output contact capacity of 5A/AC250V and communication port of RS485, Modbus (RTU) treaty.
