Beckhoff C9900-E808 CP6xxx and CP7xxx Series Push-Button Extension

Description

Integrating physical tactile controls directly alongside visualization interfaces, the Beckhoff C9900-E808 is a rugged push-button extension designed for industrial HMI environments. This extension module mounts directly to the right side of compatible 15-inch Beckhoff Control Panels and Panel PCs, specifically within the CP6x21-00xx and CP7x21-00xx series that do not feature an integrated keyboard. By combining digital bus communication with direct hardwired safety paths, the C9900-E808 provides operators with immediate physical feedback for critical machine functions while maintaining a clean, integrated panel aesthetic.

The unit features 12 square push-buttons with integrated signal lamps and a dedicated emergency stop button. To ensure high reliability and compliance with standard safety architectures, the module utilizes a dual-contact design. Primary control signals and lamp states are transmitted via CP-Link or USB interfaces, while secondary normally-open (NO) contacts and the emergency stop switch are routed to an internal terminal block for direct, fail-safe hardwiring to safety relays or PLC inputs.

Features

• Designed for direct right-side mounting on 15-inch Beckhoff CP6x21-00xx and CP7x21-00xx Control Panels and Panel PCs.
• Equipped with 12 square Siemens Signum push-buttons (30 x 30 mm) featuring integrated signal lamps.
• Includes 1 Siemens Signum emergency stop button, designed for direct hardwiring into safety circuits.
• Dual-channel signal routing: primary normally-open (NO) contacts communicate via CP-Link or USB.
• Secondary normally-open (NO) contacts are routed to an internal terminal row for direct-wire safety integration.
• Signal lamps are controlled exclusively via the system's CP-Link or USB interface.
• Removable, transparent push-button caps allow for custom, application-specific labeling.

Applications

• Automotive assembly lines and robotic work cells.
• CNC machine tool control stations.
• Process manufacturing operator interfaces.
• Heavy machinery control consoles requiring physical emergency stop and cycle-start buttons.

Installation Guidelines

• Mounting: Attach the extension housing securely to the right-hand side of the 15-inch Control Panel using the specified mounting brackets and screws. Ensure the sealing gasket is properly seated to maintain the panel's IP rating.
• Wiring: Route the emergency stop and secondary contact cables through the designated cable entries. Connect them to your safety relay or fail-safe PLC input modules using appropriate wire gauges and ferruled ends.
• Grounding: Connect the functional ground terminal of the push-button extension to the central protective earth (PE) busbar of the control cabinet to ensure electromagnetic compatibility (EMC).
