# Beckhoff CX7000

Hardware · `CX7000` · verification: source checked

The Beckhoff CX7000 is an embedded PC with an Arm Cortex-M7 480 MHz single-core processor. It has 8 multi-functional 24 V DC inputs, 4 multi-functional 24 V DC outputs, one RJ45 Ethernet interface and one USB interface. It runs TwinCAT/RTOS with the TwinCAT 3 runtime and is programmed with TwinCAT 3 via Ethernet; E-bus or K-bus terminals can be attached and are recognized automatically at startup.
