C9900-E678 | BECKHOFF | Extension à bouton-poussoir pour panneaux de commande CP6xxx et CP7xxx et PC Panel avec écran 15 pouces et clavier alphanumérique (phase de service)

Description

Designed to expand operator interface capabilities, the C9900-E678 provides dedicated tactile control layout configurations for Beckhoff industrial operator terminals. This push-button extension is specifically engineered for right-side mounting on CP6x32-00xx and CP7x32-00xx Control Panels and Panel PCs equipped with 15-inch displays and alphanumeric keyboards. By integrating physical operator controls directly next to the display unit, this module streamlines manual override operations and system monitoring in complex production environments.

The unit features 18 square Siemens Signum signal-lamp push-buttons alongside a high-visibility emergency stop button. Wiring flexibility is built-in, offering dual-path communication via standard CP-Link/USB protocols or direct terminal block wiring for integration into hardwired safety control circuits.

Features

• Specifically designed for right-side mechanical and electrical integration on compatible 15-inch Beckhoff operator panels.
• Equipped with 18 square Siemens Signum push-buttons (30 x 30 mm) with integrated signal lamps.
• Includes 1 heavy-duty Siemens Signum emergency stop button designed for direct integration into safety systems.
• Supports custom marking using insertable labels for individual push-button cap designation.
• Dual-path push-button state transmission: standard communication via CP-Link or USB (using one normally-open contact) or direct hardwiring via terminal rows (using a second normally-open contact).
• Signal lamps operate strictly via the CP-Link or USB control communication path.

Applications

• Heavy industrial machine tool stations and CNC work centers.
• Automotive assembly and plant-floor automation control panels.
• Process manufacturing operations requiring auxiliary tactile controls and localized emergency stops.

Installation Guidelines

• Ensure the host Control Panel or Panel PC (CP6x32 / CP7x32 series) is fully powered down before initiating mounting procedures.
• Securely attach the extension housing to the right-hand mechanical rail structure of the display unit using the specified mounting fasteners.
• Route internal USB/CP-Link connections carefully to prevent strain or pinching behind the display bezel.
• Directly wire the emergency stop switch terminals to the plant master safety relay or safety PLC using standard dual-channel practices.
