Product Description

1, the main features

▲ with large digital numbers display, so that the working status of thermostats and display of measured values more intuitive.
▲ adjusted using the I2C and storage technology, data protection save power.
▲ external single-phase fan with fan motivation (regular start and stop) function.
▲ with over temperature alarm, over temperature trip, fan start and stop functions.
▲ with 4-20mA analog current output and RS-485 communication.

3. Type and Classification of Function

Type	Function
Type D (Ordinary type)	Three-phase circular measurement; Three-phase circular display/maximum value display and mutual switching between two functions; Input disconnection and trouble self-check display and output; Auto start and stop of cooling fan and output; Over-temperature alarm display and output; Over-temperature tripping display and output; Display of manual/auto modes of fan, output and mutual switching; Digital compensation for value displayed in each channel; Function of "black box"; Timed start, stop and control function of fan; Detection of output status.
Type E	The same as Type D, with addition of 4~20mA analogue current output.
Type F	The same as Type D, with addition of RS485 serial communications function.
Type G	The same as Type D, with addition of one-way transformer room temperature measurement and control.
Type I	The same as Type D, with addition of one-way transformer core temperature measurement and alarm.
Type L	The same as Type D, with addition of protection and alarm function for lack of phase and failure of fan.
Type C	The same as Type D, with addition of interlock control of Pt100 and PTC on over-temp alarm and over-temp trip signal.
