XM2100.01-01-31-31-301-NN-101N1NN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-101N1NN is an embedded controller manufactured by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It functions as the automation core for machines that need synchronized motion, decentralized I/O, and fast fieldbus communication. By integrating an Intel Atom processor with industrial networking, the device executes IEC-61131-3 programs, coordinates servo drives over Sercos, and bridges sensor data to higher-level supervisory systems in assembly, packaging, and metal-forming equipment.

The controller operates from a nominal supply of 24 V DC, making it compatible with the standard control cabinet power rail used in most plant installations. Under full load, the electronics draw a maximum of 1.5 A, so power supplies can be sized with modest headroom. Internally, the board-level dissipation stays below 36 W, which simplifies passive ventilation requirements. Application code and process variables run in a protected 512 MB DDR2 RAM space, allowing mid-size motion sequences and data buffers without external memory cards. Deterministic device and axis updates are exchanged across the optical Sercos interface in cycles as short as 250 µs, giving the platform the responsiveness required for high-speed pick-and-place or register-mark following.

The aluminum enclosure stands 126.3 mm high and 100 mm wide, allowing dense DIN-rail mounting. Its front slot accepts one SD card, and a diode provides reverse-polarity protection to prevent damage during wiring. The unit carries an IP20 ingress rating, meaning touch-safe openings but no protection against spraying liquids, so it must be used in clean panels. For retained counters and recipes, it supplies 128 kB of non-volatile remanent memory, removing the need for batteries. All tasks are executed by an Intel Atom E620 600 MHz CPU whose low thermal design power aligns with Class III insulation and supports continuous operation.
