Bürkert I/O modules Type ME44 for extending the fieldbus gateway Type ME43 are used both to capture sensor signals and to specify set-point values or switching operations. The analogue modules read analogue sensor signals (e.g. from pressure transmitters) or specify analogue set-point values (e.g. for a flow controller). The further processing of input signals, e.g. via a fieldbus to a higher field level, or the targeted output of set-point signals is configured via the fieldbus gateway Type (ME43). The digital modules can be used for the feedback of switches or the output of switching signals. Once again, a configuration in Type ME43 specifies how these inputs and outputs are processed or controlled. The I/O modules Type ME44 are plugged onto a so-called backplane, which in turn is connected to the gateway Type ME43. Up to nine modules Type ME44 can be connected via three backplanes to one gateway Type ME43. Electronic modules Type ME43 and ME44 are part of the Bürkert EDIP (Efficient Device Integration Platform) concept. They facilitate the integration of field level devices (e.g. valves or sensors) in the higher control level. All I/Os of the modules comply with IEC 61131-2.
