XM2100.01-01-31-31-301-NN-101N1NN

The XM2100.01-01-31-31-301-NN-101N1NN is a compact programmable logic controller produced by Bosch Rexroth Indramat for the XM21 IndraControl Systems series. Designed as a central processing unit for decentralized motion or machine control, the module coordinates drives, I/O stations, and HMI devices through high-speed fieldbus channels. By executing deterministic control tasks inside the cabinet, it helps builders implement synchronized axis motion, process interlocks, and real-time monitoring in industrial automation cells. It integrates directly into the modular IndraControl rack, allowing scalable system expansion without altering the base footprint.

An embedded Intel Atom E620 600 MHz processor handles logic execution and communication for cyclic tasks. Paired with 512 MB of DDR2 RAM, the controller can buffer user programs, fieldbus stacks, and diagnostic services without paging delays. The electronics are energized from a 24 V DC nominal supply; under full load the unit draws up to 1.5 A, translating to a worst-case demand of 36 W. Reverse polarity is blocked by a diode so wiring errors do not damage the board. One SD card slot is available for application backups or firmware images, and the controller exports fieldbus timing that supports servo synchronization.

The housing is rated IP20, matching Protection Class III requirements for circuits that share the extra-low-voltage supply. With a vertical profile of 126.3 mm and a width of 100 mm, the module fits shallow control cabinets while leaving room for adjacent I/O slices. During operation the Sercos master can close its control loop every 250 µs, so velocity and position commands are refreshed at four-kilohertz rates. Variable data that must survive a shutdown are stored in 128 kB of remanent memory, eliminating external battery packs and permitting rapid restart sequences.
