Product Description:
The CX1020-0121 is an embedded PC module produced by Beckhoff for the CX Embedded PC Systems series. It serves as the central processing element of a modular DIN-rail automation stack, executing PLC logic, motion sequences, and HMI tasks directly on the machine. By combining PC technology with industrial I/O extensions, the unit provides deterministic control while fitting into the restricted space of a control panel.
At its core, the module uses an Intel Celeron M ULV processor running at 1 GHz, supplying adequate computing margin for motion and process tasks without the heat of a desktop CPU. The electronics rely on passive convection, so no fans are required and dust is kept away from the circuitry. Even at full load, the device sheds only 11 W, which simplifies thermal design in compact panels. Network access is provided by 2 x RJ45 Ethernet ports that handle engineering traffic and industrial protocols. Local I/O terminals are attached through a 16-bit ISA (PC104) system bus, and five diagnostic LEDs—1 PWR, 2 LAN, 1 TC, and 1 Flash—display operating states. With an IP20 protection class, the unit is intended for installation inside an enclosed cabinet.
Removable storage and peripheral expansion round out the controller. A 1 x Type I/II CompactFlash slot permits field replacement of the boot medium without opening the housing. Front-mounted 2 x USB 2.0 Type A ports allow connection of service keyboards, barcode scanners, or data loggers; each port can source up to 100 mA per port, which is suitable for low-power devices. For local visualization, the unit presents a 1 x DVI-I video interface, which shares the same 19 × 100 × 51 mm plug-in module outline as the optional USB/DVI addition, keeping the footprint consistent across CX modules. A battery-backed real-time clock maintains time stamping during power loss, while the TwinCAT PLC Runtime installed at the factory converts the hardware into a deterministic IEC 61131-3 controller as soon as power is applied.
