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

The XM4203.21-21-31-63-301-NN-NNNN-MTXANNNNN is a programmable automation controller manufactured by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. Installed inside a control cabinet, the unit orchestrates logic processing, motion coordination, and field communication, providing a central platform for machines that require synchronized multi-axis movement and deterministic data exchange.

The controller is powered from a nominal 24 V DC supply, eliminating the need for higher-voltage feeds. Its computing core is an Intel Core i3 2.30 GHz processor that runs real-time firmware and user tasks. System memory includes 2 GB of DDR3 RAM for execution buffers and 4 GB of onboard flash for program storage. A dedicated 1 × Gigabit Ethernet (RJ45) engineering port isolates commissioning traffic from the machine network. The housing complies with the IP20 ingress rating, so it must be mounted in a sealed cabinet. Physical dimensions are 200 mm wide, 74.1 mm deep, and 126.3 mm high, enabling shallow panel layouts. One USB device port and one USB host port support service imaging, data logging, or wireless adapters.

Non-volatile data, such as production counters and calibration tables, reside in 4 MB of remanent memory that survives power interruptions. The platform can coordinate up to 250 motion axes, so a single CPU is sufficient for large robotic cells or packaging lines. Reliable operation is specified up to 3000 m above sea level, accommodating high-altitude factories without derating. Installation is simplified by a mass of only 1.5 kg, and DIN-rail clips handle the load without additional bracing. Protection class III labeling confirms that all circuits run on the extra-low-voltage domain, and the cabinet earth is needed only for shielding. Together with its USB and Ethernet interfaces, these attributes let the XM21 controller integrate rapidly into modern automation architectures.
