C9900-E905 | BECKHOFF | Extension à bouton-poussoir pour panneaux de commande CP6xxx et CP7xxx et PC Panel avec écran 15 pouces sans clavier (phase de service)

Description

Designed for seamless integration with CP6xxx and CP7xxx Control Panels, the Beckhoff C9900-E905 provides a robust, right-side mounted operator interface expansion for 15-inch industrial displays lacking integrated keyboards. This push-button extension unit streamlines field operations by placing physical control elements directly adjacent to the visualization interface, facilitating rapid and tactile operator response in complex manufacturing environments.

The unit features 12 square Siemens Signum push-buttons equipped with integrated signal lamps, allowing for both input command and status feedback. For safety-critical functions, a dedicated Siemens Signum emergency stop button is mounted on the assembly. Signal transmission is highly flexible: all standard push-buttons feature dual-contact capabilities, allowing primary commands to travel via digital CP-Link or USB interfaces while simultaneously supporting direct wiring of a secondary normally-open (NO) contact via an integrated terminal row. The integrated emergency stop key bypasses interface electronics and is designed strictly for direct, hardwired integration into the system safety circuit.

Features

• Right-Hand Panel Mounting: Engineered specifically for mounting on the right side of compatible 15-inch Beckhoff Panel PCs and Control Panels.
• Tactile Operator Interface: Features 12 Siemens Signum square (30 x 30 mm) push-buttons with integrated status indicator lamps.
• Safety Integration: Includes 1 Siemens Signum emergency stop button designed for direct wiring to safety relays or fail-safe controllers.
• Dual-Channel Transmission: Supports simultaneous digital transmission (via CP-Link or USB) and hardwired terminal connection for push-button contacts.
• Customizable Labeling: Clear, removable caps on the push-buttons allow for easy insertion of custom labels and functional designations.

Applications

• Machine tool control stations requiring physical override switches.
• Automotive assembly lines utilizing 15-inch Panel PCs.
• Heavy industrial environments demanding redundant physical and digital control paths.
• Process manufacturing systems with localized safety circuit requirements.

Installation Guidelines

• Mechanical Alignment: Ensure the mounting gasket is correctly positioned between the 15-inch control panel and the C9900-E905 extension to maintain the designated ingress protection rating.
• Direct Wiring: Route the emergency stop wiring and the secondary NO terminal connections through separate, noise-shielded conduits away from high-power motor cabling.
• Power & Grounding: Verify that the host panel has a low-impedance connection to the machine ground before establishing USB or CP-Link communication paths.
