Description
The MINICOMB® EDS is an electronic pressure switch for measuring, switching and display of relative and absolute pressure and vacuum of gaseous and liquid media.
The multifunctional MINICOMB® EDS has a monochrome high-resolution OLED full graphical display, indicating the actual value in selectable pressure units. It offers the parameterization of the pressure switch according to VDMA standard and additional plain text menus. The parameters are set via the ergonomic 3-button control panel.
In addition, the EDS MINICOMB® is available with either 1 or 2 switching outputs or 1 switching output with additional analog output (4 - 20 mA).
Depending on the application different switching functions are available:
In Hysteresis-Mode both switching point SP and reset point RP can be adjusted freely. The switch switches back when the RP is reached. This allows, for example, a simple 2-point control.
With the Window-Mode defined areas can be monitored. If the process pressure is within the defined range the output is either closed or open.
The area is freely adjustable via FH (upper value) and FL (lower value).
With 2P versions, the switching modes can be configured differently for both outputs.
Switching logic (NC or NO) as well as switching delay and reset delay can be set freely in all modes.
Other features such as rotatable display indication, adjustable display power off, zero-point adjustment or password protection increase both benefit and comfort of the MINICOMB® EDS.
