• Single resistance thermometer Type Pt1000 Process connections: G ½", clamp DN 10/20 according to DIN 32676 Temperature measurement range: - 50…+ 150 Available switching functions: PNP or NPN Access to measured value, device status and settings via IO-Link interface, very easy sensor replacement The temperature sensor is used for measuring and monitoring the tempera- ture. The impact of the temperature on a resistance thermometer generates a signal which is amplified, digitised 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 occurs via the available standardised IODD. The IO-Link corresponds to the specification version 1.1. The bidirectional communication is used to read process data, parameters, diagnostic infor- mation and status messages as well as to set parameters. The two green LEDs are permanently lit as soon as power is supplied to the device. Once an IO-Link connection has been established, the LEDs flash. The switching behaviour and the switching thresholds of the digital outputs (max. 2; “PNP” or “NPN”) can - like many other parameters - be individually configured. Product variants described in the data sheet may differ from the product presentation and description. Type description Type 8418 © Christian Bürkert GmbH & Co. KG, Subject to alteration
