C9900-E878 | BECKHOFF | Extension à boutons-poussoirs pour panneaux de commande CP6xxx et CP7xxx et PC panneaux avec écran 15 pouces sans clavier (phase de service)

Description

Designed to expand physical operator control capabilities on Beckhoff human-machine interfaces, the C9900-E878 push-button extension provides integrated tactile inputs directly adjacent to the industrial display. This extension module is engineered for mounting on the right-hand side of CP6x32-00xx and CP7x32-00xx Control Panels and Panel PCs featuring a 15-inch display configuration without an integrated keyboard.

The unit combines digital integration with traditional hardwired fail-safe pathways. It houses 18 individual push-button keys outfitted with integrated signal lamps (Siemens Signum square, 30 x 30 mm layout) and a dedicated Siemens Signum emergency stop key. Signal transmission is handled flexibly: primary button operations and all signal lamp controls are transmitted over CP-Link or USB. For safety-critical integrations and independent control loops, each push-button provides a second normally-open contact routed directly to an onboard terminal row for local hardwiring.

Features

• Specifically designed for right-side mounting on Beckhoff CP6x32-00xx and CP7x32-00xx 15-inch displays.
• Equipped with 18 Siemens Signum square (30 x 30 mm) push-buttons with built-in signal lamps.
• Integrated Siemens Signum emergency stop switch, designed for direct external hardwiring.
• Customizable label inserts under push-button caps to allow application-specific marking of control functions.
• Dual-channel connection capability: digital transmission via CP-Link/USB alongside a local terminal row for direct wiring of secondary normally-open contacts.
• Signal lamps operate exclusively through digital communication channels via the CP-Link or USB interface.

Applications

• Operator panels on automotive assembly lines.
• Machine-level HMI control stations in packaging and materials handling.
• Process control desks requiring physical emergency stop and manual cycle start/stop overrides.
• Specialty machinery where software touchscreens are complemented by tactile operator controls.

Installation Guidelines

• Mounting: Mechanically align and secure the extension unit to the right-hand chassis mounting points of the compatible 15-inch control panel. Ensure gaskets are seated correctly to maintain ingress protection ratings.
• Wiring Safety: Route the emergency stop circuit separately from communication cables to prevent electromagnetic interference and comply with safety loop regulatory standards.
• Grounding: Ensure the control panel chassis is properly grounded to the machine frame to provide effective shielding for the CP-Link/USB communication lines.
