Beckhoff CP3916-0000 CP39xx Series Multi-touch Control Panel

Description

Providing high-resolution operator visualization directly at the machine, the Beckhoff CP3916-0000 integrates a multi-finger touch screen with a high-durability glass front. Designed specifically for mounting arm installation, this control panel operates as an extended display interface, allowing operators to interact with host industrial PCs located in remote control cabinets. By incorporating specialized DVI-E and USB-E 2.0 transmission standards, it maintains signal integrity over substantial distances without requiring active repeater hardware at the display unit. The robust IP65-rated housing provides full dust and liquid ingress protection, making it highly suited for demanding industrial environments.

Key Features

• High-Durability Display: Equipped with a 15.6-inch widescreen multi-touch capacitive display featuring a 1366 x 768 physical resolution.
• Extended Signal Range: Built-in DVI-E and USB-E 2.0 connection interfaces allow continuous operation up to 50 meters away from the control cabinet PC.
• Rugged Construction: Encased in a robust aluminum housing with a high-quality glass front panel to withstand harsh physical contact and chemical exposure.
• Ingress Protection: Fully rated to IP65 standards on both the housing and external connection interfaces, securing internal electronics against dust and low-pressure water jets.
• Flexible Mechanical Integration: Includes a standard connection block equipped with four M6 threaded holes arranged in a 100 x 100 mm grid for secure mounting arm installation.

Industrial Applications

• Machine-Level HMI: Direct integration onto production and packaging machinery where decentralized control interfaces are mandatory.
• Distributed Control Topologies: Ideal for systems where the host Industrial PC (IPC) must remain protected inside a main electrical cabinet, while the operator interface is positioned in the field.
• Hygienic and Food Processing: Suitable for wet environments or industries requiring routine clean-down procedures due to its IP65 glass-front configuration.

Alternative Models & Compatibility

The CP3916-0000 requires a matching sender unit on the PC side. It is typically paired with Beckhoff CU8801 USB Extended transmitter boxes or PCIe transmitter cards installed directly inside the host Industrial PC. If upgrading from older legacy CP39xx displays, confirm that the existing cable infrastructure matches the high-frequency requirements of DVI-E and USB-E 2.0 to avoid display jitter or touch input disconnects.

Application Pitfalls & Engineering Notes

When routing DVI-E and USB-E cables over the maximum specified 50-meter run, avoid placing them parallel to high-voltage lines, motor phase leads, or variable frequency drive (VFD) output cables. High electromagnetic interference (EMI) can corrupt high-speed USB-E packet transmissions, resulting in intermittent touch interface calibration losses. Ensure that the mounting arm system is mechanically stable and isolated from structural vibrations that exceed 1g.

Commissioning & Wiring Tips

Always verify that the 24 V DC power supply at the panel end accounts for voltage drop over long cabling runs. If the supply voltage dips below 19.2 V DC during startup surges, the backlight or touch controller may fail to initialize correctly. Use shielded, low-impedance cables and ground the control panel securely through the mounting arm connection block to the central machine ground.
