Beckhoff C9900-E965 CP6xxx/CP7xxx Series Push-Button Extension

Description

Integrating directly with the right-hand chassis of 15-inch CP6x22-00xx and CP7x22-00xx Control Panels and Panel PCs, the BECKHOFF C9900-E965 delivers a rugged, physical operator control interface for industrial display units that do not have integrated keyboards. Currently positioned in its service lifecycle phase, this module bridges physical hardwired pilot devices with standardized bus communication architectures.

Key Features

• 14 Integrated Push-Buttons: Square 30 x 30 mm Siemens Signum push-buttons with integrated signal lamps for visual feedback.
• Dedicated Emergency Stop: Features 1 Siemens Signum emergency stop key designed for direct, safety-compliant hardwiring.
• Dual-Channel Contact Transmission: Primary normally-open (NO) contacts are transmitted via USB or CP-Link, while secondary normally-open contacts are mapped to a physical terminal row.
• Customizable Legend Plates: Slide-in labels underneath the transparent push-button caps permit field-level custom functional tagging.
• Communication-Driven Indicators: All signal lamps are controlled exclusively via CP-Link or USB communication.

Applications

• Automotive manufacturing line HMI stations requiring physical cycle-start and manual intervention controls.
• Process industries utilizing CP6xxx and CP7xxx series panel computers for machine-level control.
• CNC machining stations where dry-contact tactile feedback is mandatory for axis jogs or tool adjustments.

Alternative Models & Compatibility

The C9900-E965 is mechanically matched to first-generation CP6x22 and CP7x22 panels with 15-inch displays. It is not compatible with multi-touch CP2xxx or CP3xxx control panels, which utilize different latching rails and profile designs. When replacing, confirm your existing host has the appropriate side-bracket recesses.

Application Pitfalls & Engineering Notes

Because the 14 signal lamps rely entirely on CP-Link or USB communication, a host PC lockup or software-driver crash will result in the lamps retaining their last state or turning off entirely, regardless of physical key actuation. Do not program critical state indications or safety status indicators on these LEDs; always route physical status lines through independent indicators if required by risk assessments.

Commissioning & Wiring Tips

When utilizing the second normally-open contacts via the physical terminal row, verify that field wiring runs do not parallel high-voltage AC lines. Shielded cabling is recommended for terminal row lines running over 10 meters inside the enclosure to eliminate cross-talk and transient noise on the 24V DC discrete inputs.
