C9900-E801 | BECKHOFF | Extension à boutons-poussoirs pour panneaux de contrôle CP6xxx et CP7xxx et PC panneaux avec écran 15 pouces sans clavier (phase de service)

Description

Interfacing directly with 15-inch display configurations, the Beckhoff C9900-E801 delivers external physical control capabilities to CP6xxx and CP7xxx Control Panels and Panel PCs. Designed specifically for display-only panels without integrated physical keyboards, this extension mounts securely to the right-hand side of the host terminal, providing immediate operator access to high-priority machinery operations. It consolidates tactile status indication and functional hardware controls into a rugged industrial housing, reducing front-panel wiring complexity while preserving mechanical integrity in harsh automation environments.

Key Features

• Direct right-side integration with Beckhoff CP6x21-00xx and CP7x21-00xx 15-inch HMI systems.
• Equipped with 12 square Siemens Signum push-buttons (30 x 30 mm) incorporating integrated active feedback lamps.
• Includes 1 dedicated high-visibility Siemens Signum emergency stop button for physical hardware circuit interruption.
• Dual-channel key contact system: First normally-open (NO) contacts map electronically via CP-Link or USB.
• Direct hardwired terminal strip access for secondary NO contacts, enabling physical wiring configurations.
• Removable transparent button caps allow customized on-site labeling and icon identification.

Applications

• Machine tool control panels requiring physical cycle start, hold, and jog overrides.
• Automotive body-shop visualization terminals where hardware safety interlocks must sit adjacent to the HMI screen.
• Process plants requiring non-software-dependent emergency shutdown triggers at operator control points.

Technical Specifications

Alternative Models & Compatibility

The C9900-E801 is configured specifically for right-side installation on 15-inch non-keyboard panels. Ensure that your host panel is the CP6x21-00xx or CP7x21-00xx configuration. If a different display size (e.g., 12-inch or 19-inch) or alternative button configuration is present in your line layout, contact engineering support to ensure correct dimensional and mounting alignment before physical deployment.

Application Pitfalls & Engineering Notes

Note that the integrated signal lamps operate exclusively over the communication bus (CP-Link or USB). Do not rely on indicator light statuses for safety-critical state feedback if active PC communication is interrupted. In circumstances where communication is severed, only the physical, hardwired secondary contact terminals remain operational.

Commissioning & Wiring Tips

To configure hardwired safety loops, route dedicated two-wire connections from the emergency stop and the secondary push-button terminal blocks back to your local safety evaluation relay or TwinSAFE system. Route digital signal cables and low-voltage command runs separately from motor-drive cables to avoid electrical interference across the communication interface.
