LD-B10 (B) series of dry variable temperature control (Universal)

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  

     deb ing.
   ▲ 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.

2．The Introduction of the Model and Function

  NOTE：The idiographic type please make reference to the manufacture outline photo and corresponding type of the back cover,  D、E、F、G、I type is carved up from idiographic function, and belongs to function character. Otherwise, it appears the finally bit in the type commonly.
