Product Description:

The CX9001-1101 is an embedded PC controller produced by Beckhoff as part of the CX Embedded PC Systems series. Designed to mount directly on DIN rail segments, it integrates PLC control, communication interfaces, and local I/O handling for compact machine-level automation. When combined with Beckhoff’s modular K-Bus or EtherCAT terminals, the unit functions as a central logic and data processor that replaces separate PLC, communication gateway, and visualization hardware.

The controller operates from a 24 V DC power source and draws the I/O terminal supply current of 2 A from the same rail. Its main memory is 128 MB RAM, which supports sizable user programs and real-time data buffers. Program code and the operating system reside in 32 MB of built-in Flash, which removes the need for rotating media. For deterministic field networking, the unit uses two 10/100 Mbit RJ45 Ethernet ports to provide independent channels for plant-network traffic or service access, while an internal 4 kB DPRAM exchanges process images with the K-Bus coupler. The housing carries an IP20 protection rating, so installation must remain inside a cabinet with limited dust exposure and no water ingress.

Control logic executes under the TwinCAT CE PLC Runtime, allowing IEC 61131-3 languages on Windows CE. Retention of critical variables across power cycles is supported by 128 kB of NovRAM, while dielectric clearance is proven to 500 Vrms, which aligns with typical low-voltage cabinet designs. Application peripherals attach through 2 × USB 2.0 Type A connectors that each supply up to 100 mA, making them suitable for low-power service tools or RFID readers. For local visualization, a DVI-I 29-pin socket drives digital or analog panels up to SXGA resolution, and the built-in K-Bus interface extends the system with up to 64 I/O terminals without external gateways.
