XM2100.01-01-31-31-301-NN-100NNNN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-301-NN-100NNNN is an industrial controller produced by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It is intended to execute PLC logic and motion coordination inside automated packaging, conveying, and assembly cells. Acting as the application processor for distributed drives and I/O, the unit provides deterministic task scheduling so actuators, sensors, and supervisory networks stay synchronized during high-speed machine cycles.

A 600 MHz Intel Atom processor, model Intel Atom E620T, supplies the real-time computing resources, while 512 MB of DDR2 RAM holds the active program code and buffers. Non-volatile program storage is delivered by a 1 GB ROM device, complemented by 128 kB of remanent memory for retaining critical variables after power loss. When the controller is linked to Sercos drives, its minimum closed-loop update reaches 250 µs, allowing velocity and torque commands to be refreshed four thousand times per second. Up to three extension modules can be attached on the right-hand bus, letting users add digital, analog, or safety I/O without increasing cabinet depth. The unit meets Protection Class III requirements, meaning all signal circuits operate on extra-low voltage levels that simplify grounding strategy.

Environmental limits support installation at altitudes of up to 4700 m without derating, and the housing carries an IP20 ingress rating that is acceptable inside a ventilated control panel. Control electronics are powered from a single 24 V DC supply, which streamlines wiring and circuit-breaker selection. Despite its processing capability, the controller weighs only 0.61 kg, helping reduce rail loading in compact cabinets. The maximum of three plug-in slices helps maintain thermal balance, and the remanent memory safeguards recipe, counter, and fault data so production resumes quickly after planned or unplanned shutdowns.
