Pressure transmitter with IO-Link interface
The pressure transmitter measures and monitors relative and absolute (on request) pressure in liquids and gases. The effect of the pressure on the sensor element generates a signal, which is amplified, digitalized, and processed.
Instead of an analogue output this device offers a digital interface IO-Link. This allows bidirectional data transfer with any IO-Link Master. Data access is done by using the available standardized IODD.
The IO-Link is in accordance to the specification version 1.1. IO-Link. The bidirectional communication is used to read process data, diagnostic information, status messages and to set parameters. The two green LEDs are permanently lit as soon as power is supplied to the device. Once an IO-Link connection is established, the LEDs flash.
The switching behaviour and the switching thresholds of the digital outputs (max. 2 pieces; “PNP” or “NPN”) can be individually configured– as well as many other parameters.
