Product Description:
The CX5120-0140 Embedded PC is designed for reliable automation control in industrial environments. The system integrates essential connectivity and expansion features. It supports flexible interface options and compact dimensions for efficient space usage.
The CX5120-0140 embedded PC comes with a DDR3 RAM (2 gb) which is fixed and non expandable. Storage options include slots for both CFast cards and microSD cards although cards are not included. It stores 1 MB of data on the CFast card for short term backup during power loss. Connectivity options feature two independent Gigabit capable RJ45 Ethernet ports (10/100/1000 Mbit/s). It is equipped with four USB 2.0 interfaces and one DVI-I video output for display connections. The system provides one optional interface slot that can be configured at the factory. Diagnostics for the PC are supported through five status LEDs, indicating power, TC status, flash access and two bus status indicators. Cooling of the PC is managed passively with no moving parts or fans.
The Beckhoff CX5120-0140 embedded PC uses a 24 V DC power supply with a (-15 to +20 %) tolerance. An internal battery backed clock maintains accurate time and date settings and the battery is replaceable. I/O terminal connections automatically detect and support both E bus and K bus systems. The embedded PC receives a current supply of 2 A for both the E bus and K bus interfaces. During peak load conditions specifically when the uninterruptible power supply (UPS) is actively charging—the system's maximum power consumption can reach up to 18 W. Typical operating consumption of the CX series embedded PC is 11 W and the E bus/K bus consumes up to 10 W (5 V/max. 2 A).
Frequently Asked Questions about CX5120-0140:
