Beckhoff CX1020-0021 CX1020 CPU Module

Description

Designed for medium-performance industrial control applications, the **Beckhoff CX1020-0021** is a high-reliability **embedded PC CPU module** that forms the core of the modular CX1020 control system. Equipped with an Intel Celeron M ULV processor running at 1 GHz, this unit delivers deterministic control performance for PLC, NC PTP, and NC I runtime environments via TwinCAT 2 software.

The module features dual RJ45 Ethernet interfaces connected via an internal switch, allowing for flexible network topologies without additional hardware. System expansion is facilitated through a Compact Flash card slot and a 16-bit ISA system bus (PC/104), enabling direct connection to Beckhoff I/O systems (E-bus, K-bus, or K-bus/IP-Link) when paired with a compatible CX1100 series power supply module.

Features

• Intel Celeron M ULV processor (1 GHz, single-core execution)
• 256 MB DDR RAM main memory, expandable ex factory to 1 GB
• Dual RJ45 10/100 Mbit/s Ethernet ports with integrated switch functionality
• Compact Flash Type I/II slot with eject mechanism for storage and operating system
• Internal battery-backed real-time clock for time and date retention (replaceable battery)
• Diagnostic LEDs for power, LAN link/activity, TwinCAT status, and flash access
• Direct integration with TwinCAT 2 PLC, NC PTP, and NC I software runtimes

Applications

• Factory automation and machine tool control
• Process monitoring and distributed control systems
• Motion control applications requiring synchronized multi-axis positioning
• Building automation and infrastructure control systems

Installation Guidelines

• Mounting: Mount horizontally on a standard 35 mm DIN rail (EN 60715). Ensure secure latching onto the rail.
• Power Connection: Power must be supplied exclusively through a compatible CX1100-xxxx power supply module connected via the system bus.
• Ventilation: Maintain a minimum clearance of 30 mm above and below the module to ensure proper convective cooling. Do not block ventilation slots.
• Grounding: Ensure the DIN rail is properly grounded to the control cabinet's common ground point to maintain EMC compliance.

Compliance and Certifications
