Beckhoff C9900-E818 CP6xxx and CP7xxx Push-Button Extension

Description

Designed for seamless physical integration with 15-inch CP6xxx and CP7xxx Control Panels and Panel PCs, the Beckhoff C9900-E818 provides an ergonomic, right-side mounted operator interface. This industrial-grade push-button extension facilitates direct tactile control alongside standard HMI visualization screens, making it ideal for machinery requiring immediate operator intervention.

The unit features 16 integrated push-buttons with signal lamps and a dedicated emergency stop button. To ensure high system reliability and safety compliance, the module utilizes a dual-contact architecture. Primary control signals and lamp states are transmitted digitally via CP-Link or USB, while secondary contacts and safety-critical circuits are routed to a terminal block for direct hardwiring.

Features

• Right-Side Mounting: Engineered specifically for CP6x31-00xx and CP7x31-00xx 15-inch display panels without integrated keyboards.
• Tactile Operator Controls: Equipped with 16 Siemens Signum square (30 x 30 mm) push-buttons featuring integrated signal lamps.
• Dedicated Safety Interface: Includes 1 Siemens Signum emergency stop key designed for direct, hardwired safety circuit integration.
• Dual-Contact Architecture: Each push-button features a primary normally-open (NO) contact transmitted via CP-Link/USB and a secondary NO contact wired directly to an internal terminal row.
• Customizable Labeling: Push-button caps support insertable labels for clear, application-specific function marking.
• Independent Lamp Control: Signal lamps are driven directly via the CP-Link or USB interface.

Applications

• Machine tool control stations
• Automotive assembly and welding lines
• Process plant visualization panels
• Custom OEM machinery control consoles

Installation Guidelines

• Mechanical Mounting: Secure the extension housing to the right side of the compatible 15-inch Beckhoff Control Panel using the provided mounting hardware. Ensure the gasket is properly seated to maintain the panel's environmental rating.
• Wiring Routing: Route the USB or CP-Link communication cable away from high-voltage AC power lines or variable frequency drive (VFD) cables to prevent electromagnetic interference.
• Safety Circuitry: The emergency stop button must be wired directly to a certified safety monitoring relay or fail-safe PLC input using the dedicated terminal row. Do not route safety-critical stop signals through the USB or CP-Link communication bus.
• Grounding: Ensure the push-button extension housing is properly bonded to the common functional ground of the main control panel assembly.
