Product Description:
The CX9020-0111 is an embedded PC module manufactured by Beckhoff as part of the CX Embedded PC Systems series. The unit functions as a compact PLC and HMI host, bringing ARM-based computing, fieldbus control, and I/O interfacing into DIN-rail automation panels. By combining control logic, networking, and visualization in one housing, it serves as the central controller for machine cells or small building-management segments.
Processing tasks are handled by an i.MX535 Cortex-A8 running at 1 GHz; this clock rate supports the instruction throughput required for IEC 61131-3 runtimes and user programs. Heat is removed through a passively cooled aluminum housing, eliminating fans and reducing maintenance in dusty cabinets. The board carries 1 GB of DDR3 RAM, providing volatile storage for the operating system, TwinCAT task contexts, and process buffers. Typical power consumption remains below 5 W, which allows dense cabinet installation without overloading low-power uninterruptible power supplies. The electrical input accepts 24 V DC with a tolerance of −15% to +20%, matching common control-circuit power rails.
The housing measures 84 × 100 × 91 mm, so it occupies roughly two standard terminal-block widths on the rail while still leaving space for couplers and relay modules. Two Ethernet ports with 2 × RJ45 connections at 10/100 Mbit/s permit separate machine and plant networks or a service loop without extra switches. Four downstream USB host ports with 4 × USB 2.0 connections support touchscreens, service dongles, or additional storage. A digital video channel uses 1 × DVI-D connection for a direct panel connection. Program and data retention are handled by dual microSD sockets with 512 MB supplied, while 128 kB of battery-free NOVRAM secures persistent variables. The single-core architecture simplifies real-time scheduling and keeps thermal gradients low inside the passive enclosure.
