1, the main features
▲ dual 4 LED display, so that the working status of temperature control and measurement value display more intuitive.
▲ adjusted using the I2C and storage technology, data protection save power.
▲ manual / automatic fan start and stop.
▲ with over temperature alarm, over temperature trip, fan start and stop functions.
▲ with 4-20mA analog current output and RS-485 communication.

|
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.

Note: Oth requirements for the temperature controller should be indicated when placing orders.
Note: If the above model, add "P", said the terminal is the active control of fan.
Third, for occasions
▲ applicable to a variety of small dry-type transformers and European box changes
▲ choose folder installed in the transformer body parts or the casing
▲ transformer cooling fan starting current up to 7A
Fourth, technical indicators
Sensor type: Pt100 (ф4 × 40)
Range :0.0-200 .0 ℃
Accuracy: ± 2.0 ℃
Operating frequency: 50Hz or 60Hz
Voltage: AC 220V
