XM2100.01-01-31-31-001-NN-111NNNN

The XM2100.01-01-31-31-001-NN-111NNNN is an embedded control unit produced by Bosch Rexroth Indramat within the XM21 IndraControl Systems series. It serves as the central processor in modular automation stations, coordinating motion, discrete I/O, and safety tasks through real-time networks. Designed for DIN-rail cabinet installation, the device replaces separate PLC hardware and unifies sequencing, diagnostics, and fieldbus handling in packaging, assembly, and material-handling equipment.

At its core, the controller runs on a Intel Atom E620 600 MHz processor that executes deterministic control loops while maintaining low power consumption. System memory includes 512 MB of RAM for program variables and buffers, and 1 GB of read-only flash for firmware and retained application code. A single Gigabit Ethernet interface enables high-speed peer-to-peer or SCADA connectivity, while one SD card slot simplifies firmware backup and recipe transfer. Local expansion relies on one USB device port for service functions and one USB host port for external peripherals. Logic and I/O power are supplied at 24 V DC, conforming to equipment class III protection for circuits with limited energy. The housing carries an IP20 ingress rating, indicating finger-safe construction intended for enclosed panels where dust and moisture exposure is controlled.

Mechanical dimensions support tight cabinet layouts: depth is 74.1 mm, height is 126.3 mm, and width is 100 mm. The unit weighs only 0.6 kg, allowing easy installation on standard top-hat rails without additional supports. Operation is specified up to 4700 m above sea level, so control performance remains stable on elevated sites such as mining or hydroelectric facilities. Passive convection cooling suffices because of the Atom processor’s low thermal load, and internal design meets protection class III, meaning no functional earth is required. One Gigabit Ethernet port, a lone SD card slot, and the pair of USB interfaces complete the physical I/O complement without expanding the footprint.
