Profile: R. K. Controls specializes in industrial automation, controls, motion, and drives products & solutions. Modular controllers are optimally designed for control tasks and for ruggedness long-term availability. They can be flexibly expanded at any time via plug-in I/O modules, funtion modules and communication modules. Depending on the size of the application, the right controller can be selected from a large range according to performance, quantity frameworks and communication interfaces. The modular controller can also be used as fault-tolerant or fail-safe systems. PC-based controllers can run on standard PC systems either as software PLCs or as slot PLCs in the form of a plug-in PCI card. Any PC application, visualization tasks, control tasks and technological functions can all be easily combined into an overall automation solution. The extensive resources of an industrial PC, such as the work memory, are used for this purpose.
