current 4~20mA, Voltage 0~5V,0~10V, modbus, rs485 Temperature Humidity Sensor Transmitter
Introduction:
HE400/HE200 series are temperature, relative humidity transmitters, adopt import components and high-performance low-power SCM design, which assure the quality and stability. This series support four kinds of output, RS485 and Standard Modbus protocol/ Voltage and Current. They have unique design features to ensure no circuit interface of themselves. They are wall-mounted and enjoy widely measuring range and high accuracy, suitable for DC16V-30V. HE400 series has LCD display temperature and humidity. In addition, it have internal and external probe. Customers can have many choices according to their demands.
