XM2100.01-01-31-31-001-NN-111NNNN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-001-NN-111NNNN is a compact embedded controller produced by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It serves as the central processing unit for decentralized motion, logic, and device communication tasks on factory floors, linking fieldbus networks with drive and I/O components while executing deterministic control sequences. Designed for cabinet installation, the unit combines industrial-grade computing hardware with standardized communication interfaces so that PLC, HMI, and networking functions can be consolidated in a single device.

Processing is handled by an Intel Atom E620 600 MHz CPU that provides sufficient cycle-time headroom for mid-range PLC applications. Volatile storage totals 512 MB, allowing sizable user programs and buffer data, while non-volatile capacity is supplied by 1 GB of internal flash for program and configuration retention. The controller draws power from a regulated 24 V DC supply and is assigned protection class III, so operation relies on a safety extra-low-voltage source. An IP20 housing protects the electronics against finger contact and settled dust inside the control cabinet, and the dimensions of 100 mm width, 126.3 mm height, and 74.1 mm depth simplify rail mounting without occupying excessive panel space.

For networked automation, the unit includes 1 Gigabit Ethernet port for real-time fieldbus gateways or network access. Local peripherals such as USB memory sticks or barcode readers connect through 1 USB host port, and a separate USB device interface supports direct PC connection. A front-accessible SD slot supports removable program backup. At a mass of 0.6 kg, the controller adds minimal load to DIN rail supports, and its aluminum heat sink permits fanless cooling. Continuous service is permitted up to 4700 m altitude, allowing operation in high-elevation facilities without derating.
