XM2100.01-01-31-31-001-NN-100NNNN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-001-NN-100NNNN is a compact programmable logic and motion controller produced by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. The unit integrates PLC functionality and real-time communication so that distributed drives, I/O modules, and HMI panels can be coordinated from a single industrial node. It is intended for cabinet installation and executes sequencing, interpolation, and safety-related tasks in small to mid-scale automation lines. Its compact format suits control cabinets where centralized logic and motion coordination must fit into limited rail space.

Its electrical subsystem runs from a regulated 24 V DC supply that is common on machining and assembly equipment. Processing is handled by an Intel Atom E620 600 MHz CPU, while control variables and buffers reside in 512 MB of DDR2 RAM. Program code is stored in solid-state memory, and a 1 GB SD card stores user data while an internal 1 GB ROM contains the operating system image. Communication with higher-level networks is delivered through a 1 Gbit/s Ethernet interface terminated on a single RJ45 port, permitting deterministic fieldbus gateways without an additional switch. A downstream USB device connection and a separate USB host socket support data transfer and service diagnostics.

The logic core and communication stack are housed in a slim enclosure that conforms to IP20, making it suitable for closed cabinets where touch-safe but unsealed electronics are acceptable. Installation space is minimized by a height of 126.3 mm, a width of 100 mm, and a depth of 74.1 mm, so multiple controllers can mount side by side on a single DIN rail. Protection Class III confirms that the device operates from the protective-extra-low-voltage range. The front panel keeps the USB and service openings accessible, allowing storage media access without disturbing neighboring modules.
