Description

The BECKHOFF CP3221-0020 is an industrial-grade Multi-touch Panel PC engineered for mounting arm installation, offering comprehensive IP65 protection across its entire aluminum enclosure. This device integrates computing power directly at the machine level, making it ideal for high-demanded operator control and visualization. Designed to fit Rittal and Rolec 48 mm tube mounting arm systems, the mechanical layout supports rotatable and tiltable adjustments from either the top or bottom, allowing flexible operator positioning.

At the core of the BECKHOFF CP3221-0020 is a 3.5-inch motherboard compatible with 6th and 7th generation Intel Celeron, Pentium, and Core i3, i5, or i7 processors. The operator interface features a high-resolution 21.5-inch multi-finger capacitive touch screen with a Full HD (1920 x 1080) display. This combination delivers stable control, crisp graphics, and responsive multi-touch interaction suitable for modern HMI and industrial software platforms.

Thermal management is executed passively through external heat sink structures embedded in the aluminum housing. To prevent internal hot spots and ensure uniform heat dissipation across all housing surfaces, an internal air-circulation fan is integrated. Storage architecture is highly configurable, featuring dedicated slots for CFast cards and 2.5-inch SSD or HDD media, alongside an onboard SATA RAID 1 controller for redundant data security.

Features

• Full IP65 protection rating across the entire enclosure, protecting against dust and liquid ingress.
• 21.5-inch multi-touch display with Full HD 1920 x 1080 resolution for clear operator control.
• Rugged aluminum housing designed specifically for mounting arm systems (Rittal and Rolec 48 mm tubes).
• Supports 6th and 7th generation Intel processors for flexible performance scaling.
• Passive external cooling paired with an internal circulation fan for balanced thermal management.
• Flexible storage expansion with CFast and 2.5-inch SATA SSD/HDD slot availability.
• Onboard SATA RAID 1 controller supporting high-reliability data storage configurations.

Applications

• Machine-level HMI visualization and plant control terminals.
• Industrial manufacturing lines requiring overhead or pedestal-mounted touch interfaces.
• Food processing and wash-down environments demanding complete IP65 sealing.
• Automated assembly and material handling systems with distributed operator stations.

Technical Specifications

Installation Guidelines

1. Verify that the mounting arm system (Rittal or Rolec with a 48 mm tube diameter) is securely installed and rated for the physical load.
2. Ensure all power feeds are fully de-energized before beginning physical or electrical installation.
3. Secure the BECKHOFF CP3221-0020 to the mounting arm adapter from the top or bottom interface as dictated by system topology.
4. Maintain a minimum of 20 cm (7.9 inches) of unobstructed space around the outer chassis heat sinks to allow adequate passive heat dissipation.
5. Route field-side cables through the dedicated IP65 wiring area and ensure all unused ports are tightly sealed with protective caps.
6. Connect the 24 V DC power supply ensuring correct polarity before energizing the system.

Replacement Recommendations

When replacing an existing panel PC with the BECKHOFF CP3221-0020, verify that your active storage cards (CFast or SSD) are properly backed up and that the installed TwinCAT licenses are deactivated or prepared for transfer. Ensure that the mechanical mounting connection matches the 48 mm tube specification. Verify that the current operating system image (Windows Embedded Standard 7, Windows 10 IoT, or Windows Server) is configured for the 6th/7th generation Intel CPU architecture to prevent driver mismatches upon initial startup.
