Product Description:
The XM4203.21-21-31-63-301-NN-NNNN-MTXSNNNNN is an industrial embedded controller produced by Bosch Rexroth Indramat for the XM21 IndraControl Systems series. The unit functions as a compact PLC and motion coordinator, allowing machine builders to integrate logic processing with drive-based control in centralized cabinets. Its design targets applications that require deterministic Ethernet communication and multi-axis synchronization. The controller provides a single platform for managing fieldbus messaging, visualization tasks, and real-time servo positioning within automated equipment.
Processing performance is delivered by an Intel Core i3 processor with two physical cores clocked at 2.30 GHz. The dual-core architecture supports distributed software tasks, including kinematic calculations for as many as 12 synchronized axes, while reserving processing capacity for HMI services. A soldered 2 GB RAM module provides working memory for the operating system and user programs, while nonvolatile data can be transferred through the single SD card slot. Three local Sercos or Ethernet extension bays accept up to 3 add-on modules for additional fieldbus or I/O interfaces. The housing measures 200 mm wide, 126.3 mm high, and 74.1 mm deep, permitting DIN rail mounting in shallow control enclosures. One USB device port supports software transfers and service diagnostics.
The controller operates from a 24 V DC supply that meets Protection Class III safety requirements, allowing installation in SELV circuits. Its IP20 enclosure protects against contact with hazardous internal parts and the entry of solid objects larger than 12.5 mm, but it does not protect against water. The unit must therefore remain inside a dry, controlled cabinet during operation. The controller supports operation at installation heights of up to 3000 m, avoiding altitude-related derating in most industrial facilities. The housing weighs 1.51 kg, which reduces the mechanical load placed on the DIN rail and panel fasteners. Its compact dimensions also leave additional cabinet space available for adjacent power supplies, I/O modules, communication hardware, and cable routing.
