DS 351 Electronic Pressure Switch with IO-Link Interface Ceramic Sensor accuracy according to IEC 60770: 0.5 % FSO Nominal pressure from 0 ... 0.4 bar up to 0 ... 600 bar gauge from 0 ... 0.6 bar up to 0 ... 600 bar absolute Digital output signal IO-Link according to specification V 1.1 smart sensor profile data transfer 38.4 kbit/sec Switchable output signal PNP / NPN / 4 … 20 mA / 0 … 10 V The DS 351 has been designed for applications in machine tools or pneumatic and hydraulic systems. In combination with the optionally available PVDF pressure port also the usage in aggressive media is possible, whereby material resistance has to be checked in advance. It offers an IO-Link interface as standard, which provides process data, diagnostics reports and status messages as well as other features, which are helpful for service / maintenance and condition analysis of a machine or plant. The parameters are set either also via control level or via VDMA-compliant menu system, which can be carried out in situ by using two buttons. indication of measured values on a 4-digit LED display rotatable and configurable display module The multiple, infinitely variable adjustability of the display as well as the individually parameterizable output signal (switching or analogue signal (mA / V)) support the user in realizing the measurement task. parameter settings via IO-Link or menu (VDMA-conform) additional information via IO-Link accessible Plant and machine engineering different mechanical connections pressure port in PVDF Environmental engineering (water – sewage – recycling) customer specific versions BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein
