Product Description:

The CX5120-0163 is a part of CX PC systems series produced by Beckhoff, tailored for industrial automation. It supports installation of fieldbus interfaces such as EtherCAT, PROFIBUS and PROFINET. The system incorporates a strong construction to achieve vibration and shock standard compliance.

The CX5120-0163 PC system has dimension measurement of 122 mm length, 100 mm width and 92 mm height while carrying about 975 grams in weight. Its power supply requirement is 24 VDC with a tolerance range of ±20% and its maximum power consumption reaches 18 W. It offers IP20 protection rating while operates between -13 °F to +140 °F temperature and can handle exposure to relative humidity up to 95%. The CX5120 PC system features integrated processing speed of 400 MHz base and 792 MHz boost operation rates. The status information of power supply, bus communication and optional interfaces appears on diagnostic LED indicators. It has K-bus and E-bus systems for terminal communications and links the systems automatically. The required installation space includes a DIN rail which needs at least 30 mm of empty space for ventilation as it self-cool. The CX5120 PC system has an Intel Atom E3815 processor which functions at 1.46 GHz clock speed. It has an onboard RAM of 2 GB DDR3 memory.

The CX5120-0163 PC system works with Windows 10 IoT Enterprise 2019 LTSC 32-bit as its operating system platform. It has two built-in storage slots to support CFast and MicroSD cards. The CX5120 PC system offers two separate Gigabit Ethernet ports to provide a speed range of 10/100/1000 Mbit/s and has four 2.0 Type-A ports for USB connectivity. Through its DVI-I interface it delivers digital and analog display output of 1920 × 1200 resolution.

Frequently Asked Questions about CX5120-0163:

Q: How does the K-bus system improve terminal communication in CX5120-0163?

A: K-bus enables flexible signal wiring and data handling between terminals without additional software. This reduces latency and improves modular I/O scalability.

Q: Why is the Intel Atom E3815 processor used in the CX5120-0163?

A: The Intel Atom E3815 balances low power consumption with 1.46 GHz processing, making it efficient for 24/7 embedded industrial control tasks.

Q: How does the DIN rail spacing impact cooling performance in CX5120-0163?

A: Maintaining 30 mm of clearance on the DIN rail allows the passive cooling system to dissipate heat efficiently. This eliminates the need for active fans and reduces maintenance.

Q: What is the role of E-bus in the CX5120-0163 PC system?

A: E-bus provides high-speed communication with EtherCAT terminals, allowing synchronized I/O operations in real-time industrial automation setups.

Q: Why does CX5120-0163 only support 32-bit Windows 10 IoT Enterprise?

A: The 32-bit OS ensures compatibility with legacy industrial applications while reducing memory overhead on embedded platforms.
