Product Description:
The CX9020-0112 represents an Embedded PC for controlling industrial processes by Beckhoff. It integrates control, communication and display functions in one device. It includes 1 GB DDR3 RAM and 128 kB NOVRAM with ~63 kB usable storage. It supports TwinCAT 2 NC runtime for motion control applications. This model belongs to the CX Embedded PC Systems series.
The CX9020-0112 has 1 GHz single-core ARM Cortex-A8 processor. The unit supports two MicroSD slots for OS and application data. Two RJ45 Ethernet ports support 10/100 Mbps speeds. A DVI-D port outputs up to 1920×1200 resolution over 5 meters. It can support OPC and ADS for HMI and PLC connectivity. It operates on Windows Embedded Compact 7 with Beckhoff Device Manager for web-based configuration. The model offers a fanless passive cooling system for quiet operation. Voltage input is 24 V DC with a tolerance of -15% to +20%. The front flap gives access to a battery-backed RTC. It includes automatic detection for K-bus or E-bus power terminals. Protection class is rated at IP20. Each of the four USB 2.0 Type-A ports offers an output current of 500 mA. It includes an internal switch. It does not support EtherCAT. It requires a 4 A power supply and uses spring terminals for connections. Mounting is horizontal through DIN rail only.
The Beckhoff’s CX9020-0112 is built for compact, efficient and rugged automation tasks. Its NOVRAM supports delta-based storage for variable retention. Dimensions are 84 × 100 × 91 mm and it weighs 590 g. It operates between -25°C and +60°C. Storage should remain between 0°C and 30°C with the battery removed. It offers streamlined configuration through Beckhoff’s Device Manager interface. Its performance and size make CX9020-0112 ideal for embedded industrial environments.
