With its integrated pressure measurement cell, 4-digit display and 4 switching outputs, the EDS 1700 offers the user all the advantages of a modern electronic pressure switch. 4 switching points and switch-back points can be adjusted very simply and independently of one another using the keypad.

For optimum integration in monitoring systems (e.g. with PLC), an Analog output (4 to 20 mA or 0 to 10 V) is also available.

The main areas of application of the EDS 1700 are in hydraulics and pneumatics. The instrument is ideal for use where frequent switching cycles (several million), stable switching point accuracy or simple and precise adjustability are required.

Special Features

N/A

  • Integrated pressure sensor with strain gauge on stainless steel membrane
  • Simple operation via key programming
  • 4 limit relays, switching points and switch back points can be adjusted independently
  • Analog output signal selectable
  • Many useful additional functions
  • Optional mounting position (pressure connection on the top/ bottom, keypad and display can be turned through 180°)
  • Can be set to display values in any unit of measurement e.g.: kN, kg, psi

Setting Options

N/A The core of the unit is a microprocessor which provides many useful extra functions in addition to normal pressure switch operation. It is possible, for example, to activate switching delay times to prevent fast pressure peaks from triggering an unwanted switching cycle. All settings are made using the keypad.

Setting Ranges of the Switching Points

N/A

  • Switching point relay 1 to 4: 1.5 % to 100 % FS
  • Switch-back relay 1 to 4: 1 % to 99 % FS or alternatively switch-back hysteresis 1 to 4: 1 % to 99 % FS

Note for Setting Ranges of the Switching Points

 N/A FS (Full Scale) = Relative to the Full Measurement Range

Additional Setting Options

N/A

  • Switching direction of the relays 1 to 4 (N/C or N/O)
  • Switch-on delay relays 1 to 4 in the range 0.00 .. 90 seconds
  • Switch-off delay relays 1 to 4 in the range 0.00 to 90 seconds
  • Switch-back mode (either switch-back point or switch-back hysteresis)
  • Display of the actual pressure, a switching point or of the peak value
  • Display filter (slow/medium/fast)
  • Display range scale individually adaptable (bar, psi, user-selectable)
  • Measurement unit (bar, psi) is displayed
  • Analog output (4 to 20 mA or 0 to 10 V)
  • Programming disable
