The CML75.1-3P-905-NA-NNN-NW is manufactured by Bosch Rexroth Indramat for the CML IndraControl Hardware series. Serving as the central processor inside modular automation cabinets, the device coordinates motion, I/O, and field communication tasks for distributed machinery cells. The module is sized for a DIN-rail bus and links electrically to neighboring expansion slices so that motion axes, safety functions, and communication couplers can be consolidated in one narrow controller row.

Its processing platform is identified as the CPU design variant 1, meaning the performance, instruction set, and onboard coprocessor mix correspond to the first option in the 75 family. Working memory includes 4096 MB of DRAM for real-time program execution and data buffering, while nonvolatile storage for retentive tasks relies on a compact 16 MB SRAM device that preserves critical variables during power cycles. There is no NvRAM fitted, so retentive space is restricted to the static SRAM segment and any external memory cards chosen by the user. Fieldbus connectivity is integrated through a PROFIBUS interface, allowing the controller to exchange cyclic telegrams with drives, operator panels, and distributed I/O nodes over the widely adopted 12 Mbit/s RS-485 network.

Thermal management is simplified because the electronics are supplied without a fan; passive convection is adequate for the specified ambient envelope when the module is mounted upright in the panel. The electronics sit inside an inline housing that maintains a common profile height with companion I/O slices, reducing cabinet depth. Hardware identification within the family is marked as series 75, which aligns firmware packages and diagnostic tools to that generation. As a Control Main Unit, the device exposes the back-plane bus master, timing source, and power distribution tracks required by subordinate modules without additional rack hardware.
