XM4203.21-21-31-63-301-NN-NNNN-MTXANNNNN by Bosch Rexroth Indramat

Bosch Rexroth Indramat manufactures the XM4203.21-21-31-63-301-NN-NNNN-MTXANNNNN, an embedded controller in the XM21 IndraControl Systems series. The product functions as a combined PLC and motion coordinator, delivering deterministic command sequences to drives and distributed I/O across modern production lines. By coupling a real-time operating kernel with standardized fieldbus access, it manages synchronized kinematic groups and consolidates multiple control tasks on one platform while preserving tight cycle timing.

Central processing is supplied by an Intel Core i3 2.30 GHz CPU, providing numeric throughput for axis interpolation, program execution, and onboard diagnostics. The controller draws logic power from a single 24 V DC rail, simplifying cabinet wiring and supporting ride-through with external UPS modules. A factory-installed memory set combines 2 GB of DDR3 RAM for variable handling with 4 GB of solid-state storage for the operating system and user projects. An engineering interface exposed as 1 × Gigabit Ethernet (RJ45) permits download, trace, and remote service functions without occupying field ports. The platform can address up to 250 servo or hydraulic axes through Sercos and EtherCAT channels. Ingress protection is rated at IP20, indicating finger-safe shielding for installation inside ventilated control enclosures.

The housing has a depth of 74.1 mm, while the width and height measure 200 mm and 126.3 mm, so multiple controllers can mount side by side on DIN rail. Operating mass is kept to 1.5 kg, easing door-mounted installation and reducing vibration stress on terminals. One USB device port and one USB host port facilitate local backup, keyboard, or service dongle attachment, and 4 MB of remanent memory secures nonvolatile machine data across power cycles. Full performance is maintained up to 3000 m above sea level, and the electronics conform to protection class III requirements for extra-low-voltage systems.
