RE 95203/11.07 RC Bosch Rexroth AG /20 Description The BODAS controller RC36-20 has been designed as a universal central controller for complex mobile working machines. State-of-the-art 32-bit TriCore technology, a clock frequency of 150 MHz and parallel processing enable the RC36‑20 to move in completely new dimensions in terms of performance, previously the reserve of much larger PLC systems.
