Product Description:
The CX5140-0162 is an embedded PC module produced by Beckhoff within the CX Embedded PC Systems series. Designed for DIN rail installation, the unit serves as a compact PLC and motion controller that links field I/O with higher-level networks in industrial automation cells. It executes user programs directly on its integrated hardware and provides deterministic task scheduling for machine sequencing, process visualization, and data exchange with supervisory systems. This architecture allows control and communication tasks to run locally without requiring a separate industrial computer.
At the heart of the controller is an Intel Atom E3845 processor with four physical cores that runs at 1.91 GHz. The configuration supports the TwinCAT 2 NC PTP Runtime, allowing the controller to perform point-to-point motion tasks while also handling HMI services and protocol stacks. System memory consists of 4 GB DDR3 RAM, while a dedicated 256 MB graphics buffer feeds the onboard DisplayPort interface. Two gigabit-capable Ethernet adapters are exposed through 2 × RJ45 connectors, enabling separate real-time and office networks. The electronics receive power from a 24 V DC cabinet rail, and typical consumption remains within 16 W during full CPU load. These processing and networking resources support deterministic cycle times for servo axes and I/O scans.
The housing measures 142 mm × 100 mm × 92 mm and fits between adjacent terminal blocks without overhang. An internal supercapacitor provides an integrated uninterruptible power supply that preserves system variables for one second before shutdown begins; during this interval, total demand may peak at 23 W. The housing provides IP20 protection, so installation inside a switchgear enclosure is recommended. Signal insulation withstands 500 V dielectric testing relative to the supply rail, and the single-source power feed simplifies EMC-compliant routing. External peripherals connect through 4 × USB 2.0 Type-A sockets, each of which supplies 500 mA for devices such as touch panels or USB drives. The compact enclosure and moderate power demand help limit space requirements and heat accumulation inside the control cabinet.
