BECKHOFF C9900-E668 CP6xxx and CP7xxx Push-button Extension

Description

Designed for seamless integration on the right-hand side of operator interfaces, the C9900-E668 push-button extension provides auxiliary physical controls for industrial environments. This tactile extension panel is specifically designed for Beckhoff CP6x22-00xx and CP7x22-00xx Control Panels and Panel PCs equipped with 15-inch displays and numeric keyboards.

The unit features 14 square push-button keys with integrated signal lamps (Siemens Signum, 30 x 30 mm) and one dedicated Siemens Signum emergency stop button. Electrical integration is highly versatile: signal lamps and primary normally-open (NO) contacts are transmitted directly via CP-Link or USB interfaces, while a secondary independent set of normally-open contacts is routed to a terminal strip for direct hardwiring. The emergency stop switch is fully independent and directly wireable for safety-critical integration.

Features

• Panel Compatibility: Engineered for right-side mounting on Beckhoff CP6x22-00xx and CP7x22-00xx control units with 15-inch screens.
• Operator Interface: 14 square Siemens Signum push-buttons (30 x 30 mm) with integrated signal illumination.
• Safety Elements: Integrated Siemens Signum emergency stop button, designed for direct hardwiring into safety circuits.
• Customizable Legend: Insertable labels for push-button caps allow for clear, application-specific functional marking.
• Dual Contact Paths: Primary push-button signals transmit over CP-Link or USB, while secondary normally-open contacts terminate at a terminal block for independent wiring.
• Bus-Controlled Illumination: All signal lamps are driven exclusively via CP-Link or USB.

Applications

• Automotive manufacturing assembly lines and robotic cells.
• Special purpose machinery requiring direct physical operator overrides.
• Process control systems needing reliable local emergency stop controls alongside HMI visualization.
• Heavy industrial control environments utilizing Beckhoff Panel PCs.

Installation Guidelines

• Ensure all power to the host Control Panel or Panel PC is disconnected prior to mounting the extension.
• Securely attach the extension housing to the right-hand side of the main display chassis using the specified mechanical mounting kit.
• Connect the USB or CP-Link internal cables to the corresponding internal headers of the panel PC.
• Route secondary contact and emergency stop wiring through proper cable glands or strain reliefs to prevent tension on the internal terminal row.
• Verify continuity and correct function of the Emergency Stop circuit before commissioning the machine.
