Beckhoff CX1100-0002 Power supply units and I/O interfaces for CX1010/CX1020

The Beckhoff CX1100-0002 is the fundamental power and communication base module for the compact and powerful CX1010 and CX1020 Embedded PC series. It serves as the critical link between the CPU module and the wider automation world, providing both the operating power and the essential fieldbus and I/O interfaces required for a complete control system.

This module is the backbone of the CX1000 system, transforming the compact CPU into a fully functional industrial PC and PLC platform ideal for small to medium-sized machines and decentralized control tasks.

Key Features and Benefits

• Integrated System Power Supply: The CX1100-0002 accepts a wide-range 24 V DC supply (19-30 V DC), providing stable and filtered power to the entire stack, including the CPU and any additional I/O modules.

• EtherCAT Communication Ports: Features two EtherCAT RJ45 ports, enabling seamless integration into any EtherCAT network. It allows the CX1000 system to act as an EtherCAT slave device or a compact master for smaller networks.

• DVI-I Video Interface: Provides a direct connection for a monitor or control panel via the DVI-I port, supporting both digital and analog (VGA via adapter) signals for local visualization.

• Dual USB 2.0 Ports: Offers connectivity for peripheral devices such as a mouse, keyboard, USB sticks, or barcode scanners, facilitating easy commissioning, data logging, and local operation.

• Legacy K-Bus Connection: Includes a connection for the classic Beckhoff K-Bus I/O system, allowing for cost-effective expansion with a vast existing portfolio of Beckhoff I/O terminals.

• Compact and Rugged Design: Built to withstand the demanding conditions of industrial environments with a wide operating temperature range and robust electrical specifications.

Primary Functions in the System

1. Central Power Hub: It distributes the 24V DC input power to the connected CPU module (CX1010 or CX1020) and any subsequent I/O modules in the stack, ensuring reliable operation.

2. Network Communication Gateway: The integrated 2-port EtherCAT switch is the system’s lifeline to the control network, ensuring high-speed, deterministic data exchange with other drives, I/O, and sensors.

3. Local Connectivity Center: By consolidating DVI, USB, and the K-Bus interface, it provides all necessary ports for local user interaction and system expansion without requiring additional hardware.
