XM2100.01-01-31-31-001-NN-108N3NN by Bosch Rexroth Indramat

The XM2100.01-01-31-31-001-NN-108N3NN is a programmable logic controller manufactured by Bosch Rexroth Indramat as part of the XM21 IndraControl Systems series. It serves as the central processing component in industrial automation cells. The controller executes control algorithms, exchanges data with higher-level systems, and directs distributed I/O over real-time fieldbuses.

Processing tasks are handled by an Intel Atom E620 (600 MHz) processor, and the integrated Ethernet interface supports deterministic communication at 1 Gbit/s. The unit draws a typical 24 W under standard load while peaking at 36 W, so cabinet thermal planning can usually be based on nominal dissipation. Control electronics are supplied with 24 V DC, and a diode provides reverse-polarity protection to help prevent damage during wiring. When deployed as a Sercos master, the device can close control loops every 250 µs, enabling synchronized motion across multiple drives. Up to 63 S20 I/O modules can be attached, each fed by a 2 A backplane supply current, and the controller's internal fuse is rated at 2.5 A to isolate faults. Transient surges up to 1500 W are suppressed by the onboard protection network.

The enclosure carries an IP20 rating, so it must be mounted inside a protective panel with controlled airflow. A maximum of 3 extension interface modules can be clipped to the right-side housing without exceeding bus timing or load limits. Operation is permitted up to 4700 m above sea level, and derating is unnecessary below this height because internal components are suited to the reduced air density. The DC supply path is protected against lightning-induced transients by the onboard suppression network. The unit weighs 0.7 kg, allowing DIN-rail installation without additional support brackets. Overall heat dissipation remains within the stated limit even when all S20 slots and fieldbus links are active.
