Product Description:

The Beckhoff CX8091 has an ARM926EJ-S 32-bit microcontroller with a clock rate of 400 MHz to provide effective performance in industrial control systems. It has 64 MB of RAM and 512 KB of flash memory for storage of PLC programs and data, which includes 2MB for firmware and 1 MB for the file system. It has several communication interfaces such as Ethernet, USB device, CANopen (slave), and RS232/RS485.

In addition, the CX8091 provides fieldbus interface capabilities with Modbus TCP/IP, CANopen, and various serial communication formats. This unit is energy-efficient with a power supply of 24 V DC as well as a typical power consumption of 2.5 W only. It has a DIN rail mounting type, and it measures 64 mm x 100 mm x 73mm in size. Its enclosure is protected and IP20 rated, which means this PC is compact and housed in an IP20-rated enclosure. It can work within a temperature range of 0 to +55 degrees Celsius and is designed to be stored at a temperature range of -25 to +85 degrees Celsius. Twincat is compatible with CAT Sade USB High-Speed, CAT3 USB or CAT4 USB, thus providing flexibility in software development.

Due to the clock frequency of 400 MHz, the CX8091 is capable of running industrial operations effectively. Its high speed is useful for performing automation functions and real-time processing, making the device ideal for use in high-level control systems. The CX8091 unit features 255 I/O terminals or bus interfaces, thus, it is very flexible. This makes it possible to link several input/output modules for diverse applications, ranging from basic control systems to advanced industrial applications.
