Product Description:
The XM4203.21-21-31-63-301-NN-NNNN-MLCBNNNNN is an industrial control unit built by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It serves as the central processing component in distributed automation cells, executing motion sequences and logic while interfacing with servo drives and plant-level networks.
Processing is handled by an Intel Core i3 2.30 GHz CPU that contains 2 cores, giving the controller multi-task capability for logic, HMI, and real-time fieldbus duties. The platform carries 2 GB of RAM for volatile program data and 4 GB of solid-state mass storage for the operating system and application files. A 4 MB remanent memory segment retains variables after power loss, assisting with recipe and fault logging. Control electronics are supplied from a 24 V DC cabinet circuit, so standard machine power supplies can be used without conversion.
Field communication uses two Sercos III ports for deterministic drive and I/O exchange, a single 1 Gbit/s Ethernet port for plant networking, and three extension module slots that accept digital, analog, or safety I/O carriers. One USB device interface supports engineering uploads, while a USB host port allows data logging or wireless adapters. The housing meets an IP20 ingress rating and measures 126.3 mm in height, 200 mm in width, and 74.1 mm in depth, enabling installation on shallow DIN rails. Weight is 1.35 kg, so the unit can be mounted on light sub-panels without additional bracing.
