1, the main features
Interference with the new hardware and software design ▲ have strong interference rejection capability, to meet international standards (IEC61000) index requirements.
▲ adjusted using the I2C and storage technology, data protection save power.
▲ first designed for the user "analog output state detection" function, ergonomic design greatly facilitate the users to install before the temperature controller testing and debugging.
▲ fan motivation (regular start and stop) feature, to avoid long periods of time to run the fan locked rotor corrosion.
▲ with 4 ~ 20mA analog current output. With RS-485 asynchronous communication.
