XM2100.01-01-31-31-301-NN-108N3NN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-108N3NN is a compact programmable controller produced by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. Acting as the central processor in distributed automation, it coordinates motion, logic, and fieldbus communication for machines and production lines. The hardware combines its computing core, communication interfaces, and power conditioning so it can run IndraWorks application code in real-time control environments.

The controller operates from a nominal supply of 24 V DC, allowing direct connection to standard control cabinet power rails. Under maximum load, its internal consumption reaches 36 W, which helps determine power supply capacity and cabinet heat load. Processing tasks are handled by an Intel Atom E620T 600 MHz processor that balances deterministic performance with low heat generation. Program variables and buffers are stored in 512 MB DRAM, while cyclic data exchange with servo drives is handled through Sercos III and can reach a minimum cycle time of 250 µs. Two onboard Sercos III ports support line or ring network topologies, and up to three extension modules can add more fieldbus or local I/O functions.

Installation limits are straightforward for panel-based automation systems. The housing has an IP20 degree of protection, so the unit is intended for mounting inside an enclosed cabinet. Electronic components operate over a temperature range of -25 to 60 °C, which supports both cold starts and use near warm machinery. Reliable operation is maintained at elevations up to 4700 m, covering most terrestrial installation sites without added cooling measures. For program code and diagnostics, the controller provides 1 GB of non-volatile memory, and 128 kB of remanent memory preserves important variables during power cycles.
