Beckhoff CX7080

The Beckhoff CX7080 is an embedded PC in the CX7000 series with an Arm Cortex-M7 processor. It provides eight multi-functional 24 V DC inputs, four multi-functional outputs, Ethernet, and RS232/RS485 serial interfaces. It runs TwinCAT/RTOS with TwinCAT 3 runtime and connects to E-bus or K-bus terminals that are recognized automatically at startup.
