BECKHOFF CX5120-0155 Embedded PC

Description

The BECKHOFF CX5120-0155 is an Embedded PC belonging to the CX5100 series, designed for DIN rail mounting in industrial automation environments. Powered by an Intel Atom E3815 processor with a clock frequency of 1.46 GHz and a single core, this controller is engineered to execute PLC, motion control, and visualization tasks within a compact housing. It is equipped with 2 GB of DDR3 RAM and operates under the Microsoft Windows 10 IoT Enterprise 2016 LTSB operating system, featuring the pre-installed TwinCAT 3 runtime (XAR) corresponding to performance level 40.

System integration is facilitated by two independent 10/100/1000 Mbit/s Ethernet ports, a DVI-D interface for display connection, four USB 2.0 ports, and one optional interface slot. The device supports automatic recognition of connected BECKHOFF I/O systems, accommodating both E-bus and K-bus terminals directly. For data integrity and safe shutdown procedures, the unit includes an integrated 1-second uninterruptible power supply (UPS) backed by persistent memory on a Compact Flash card, alongside an exchangeable battery-backed internal clock.

Installation Guidelines

1. Ensure all power sources are switched off and isolated before beginning mechanical installation or wiring.
2. Verify that the DIN rail is securely mounted and properly grounded according to local industrial standards.
3. Mount the BECKHOFF CX5120-0155 onto the DIN rail by engaging the top lip and pressing down until the locking mechanism clicks into place.
4. Connect the 24 V DC power supply to the designated power terminals, ensuring correct polarity and observing the allowable voltage range (-15 % / +20 %).
5. Attach any required E-bus or K-bus terminal blocks to the right side of the Embedded PC, ensuring physical engagement and automatic bus connection.
6. Connect necessary network cables to the RJ45 Ethernet ports and peripheral devices to the USB or DVI-D interfaces.
7. Power on the system and verify operational status via the diagnostic LEDs (power, TwinCAT status, flash access, and bus status).
