ETS 1700 Electronic Temperature Switches for separate temperature probe

ETS 1700

The electronic temperature switch ETS 1700 is used mainly together with the temperature probe TFP 100, which was specially developed for tank mounting.

The 4-digit display can indicate the actual temperature, one of the switching points or the maximum temperature value.

The maximum temperature indicates the highest temperature which has occurred since the unit was switched on or was last reset.

The 4 switching outputs can be used to control heating and cooling processes in hydraulic systems, for example. Four switching and switch-back points which are independent of each other can be adjusted very simply via the keypad.

An analog output (4 .. 20 mA or 0 .. 10 V) is also available for integration into monitoring systems (e.g. with PLC).

Special features:

  • 4-digit display
  • Simple operation due to key programming
  • 4 limit relays, switching points and switch back points can be adjusted independently
  • Optional analog output signal (4 .. 20 mA or 0 .. 10 V)
  • Many useful additional functions
  • Optional mounting position (sensor connection on the top/ bottom, keypad and display can be turned through 180°)

Setting options:

The microprocessor integrated into the ETS 1700 enables many useful extra functions in addition to the switching functions, when compared with a normal mechanical temperature switch. It is possible, for example, to activate switching delay times or to change the relay switching direction. All settings are made via the keypad.

Setting ranges of the switching points and switch-back hysteresis:

  • Switching point relays 1 to 4: 1.5 .. 100 % of the measuring range
  • Switching point relays 1 to 4: 1 .. 99 % of the measuring range or alternatively
  • Switch-back hysteresis 1 to 4: 1.. 99 % of the measuring range

Additional functions:

  • Switching direction of the relays 1 to 4 (N/C or N/O function)
  • Switch-on delay relays 1 to 4 in the range from 0.0 .. 900.0 seconds
  • Switch-off delay relays 1 to 4 in the range from 0.0 .. 900.0 second
  • Switch-back mode (alternatively switch-back point or switch-back hysteresis)
  • Display of the actual temperature, a switching point or of the peak value
  • Display range individually selectable in °C or °F
  • Measurement unit (°C, °F) is displayed
  • Analog output (4 .. 20 mA or 0 .. 10 V)
  • Programming lock
