EDS 601 Series

Hydac_Press Switch_EDS601

The EDS 601 is an electronic two-channel pressure switch with display and analog output. Its digitally adjustable switching points and switching hysteresis make it particularly suitable for applications requiring frequent change-overs or accurate switching point settings.

The variety of setting parameters ensures versatility for use in all control and monitoring tasks in hydraulics, pneumatics, process controls and in general test and control engineering applications.
