CX8190

CX8190 is a Beckhoff embedded PC in the CX Embedded PC Systems series. It uses a single-core Arm Cortex-A9 processor running at 800 MHz to execute control tasks, with a minimum task time of 500 µs. Its 512 MB of DDR3 RAM supports active processes, while 512 MB of microSD flash memory provides nonvolatile storage. Passive cooling dissipates operating heat without a fan.

The fieldbus interface uses Ethernet and supports RT-Ethernet, ADS UDP, ADS TCP, EAP, and Web Services for industrial communication and data exchange. One RJ45 Ethernet port provides a physical network connection at 10/100 Mbit/s. The terminal bus supports either K-bus or E-bus terminals, allowing compatible I/O modules to be connected.

The unit operates from a 24 VDC power supply and provides a 2 A I/O supply. Maximum E-bus or K-bus power is 10 W at 5 V and up to 2 A, supplying connected bus terminals. Maximum power consumption and maximum power draw are both 4 W. Power draw can reach 9 W when the UPS is active. The integrated UPS provides a one-second buffer time for short power interruptions. Its UPS memory consists of 1 MB on the microSD card, and the UPS storage capacity is also 1 MB on microSD.

The housing measures 71 mm in width, 100 mm in height, and 73 mm in depth, and the unit weighs 230 g. Its IP20 protection rating guards against contact with fingers and solid objects larger than 12.5 mm but does not provide water protection.
