Wika Models D-20-9, D-21-9 Pressure transmitter with CANopen® interface

CANopen is receiving more acceptance in the mechanical engineering for standard applications too. WIKA accommodates this tendency by offering the D-2X-9, extending WIKA’s range of products with an efficient, yet cost-effective pressure transmitter with CANopen interface. This series of pressure transmitters has been carefully designed to cover the majority of industrial applications with instruments readily available from stock. Compact design and robust construction make these instruments suitable for all applications in machine construction, process control, laboratory or quality and materials testing equipment. All wetted parts are made of stainless steel and are hermetically welded. Therefore there is no need for additional sealing material, which could possibly react with the pressure medium.

The integrated interface has been designed according to the CANopen specification DS-301 of the user organisation CiA. The device profile DS-404 which is used here, has been specially designed by the CiA for the use in measuring and control instruments. This guarantees the compatibility with other CANopen-systems according to CiA specification. A galvanic isolation of the output signal can be offered as an optional extra. The D-2X-9 supports, among others, LSS, Node Guarding, Heartbeat, synchronous and asynchronous data transmission. The Baud rate can be adjusted from 20 K Baud up to 1 M Baud. Configuration via a DIP switch is offered as an optional extra. For easy configuration the tool EasyCom CANopen is available.
