XM4203.21-21-31-63-301-NN-NNNN-MTXSNNNNN

The XM4203.21-21-31-63-301-NN-NNNN-MTXSNNNNN embedded controller is produced by Bosch Rexroth Indramat as part of the XM21 IndraControl Systems series. Designed for cabinet installation, the unit functions as the central logic and motion platform in automated machinery. By combining standardized fieldbus connectivity with real-time task handling, it orchestrates servo drives, sensors, and safety devices so that production sequences stay synchronized and repeatable.

Its processing hardware centers on an Intel Core i3 processor equipped with two physical cores clocked at 2.30 GHz. This combination supports deterministic cycle times required for motion loops and PLC tasks. Application variables and buffering are stored in 2 GB of DDR memory, allowing sizable user programs and diagnostic data without external storage dependence. Control electronics draw power from a stabilized 24 V DC supply, simplifying integration with common machine power rails. The housing carries an ingress rating of IP20, indicating that conductors must be protected from direct contact and that the controller is intended for clean, ventilated enclosures rather than exposed production zones.

Motion scalability is provided by support for up to 12 synchronized axes while still accepting as many as 3 slice-style extension modules for added I/O or communication functions. Reliable operation is maintained up to 3000 m above sea level, which covers most factory elevations without derating. The unit weighs only 1.51 kg, and its 200 mm width, 126.3 mm height, and 74.1 mm depth let it fit on compact DIN rails. One SD card slot enables program backup, and a single USB device port facilitates service uploads. The unit belongs to Protection Class III, so functional safety circuits must remain separated from higher voltages.
