C9900-G055 | BECKHOFF | Extension compacte à boutons-poussoirs pour panneaux de contrôle multi-touch CP39xx en mode paysage et PC panneaux CP32xx-1600 et CP37xx-1600

Description

Designed directly for physical system integration below landscape multi-touch CP39xx Control Panels and CP32xx-1600 or CP37xx-1600 Panel PCs, the Beckhoff C9900-G055 provides a rugged, tactile mechanical operator interface for safety-critical and high-frequency manual control actions. By combining direct mechanical switching with standard industrial bus interfaces, this extension bridges physical operator control with software-based visualization environments. The panel features durable RAFI RAFIX 22FS+ series components, including a dedicated high-reliability emergency stop actuator. By routing safety-critical break contacts independently from the system USB bus, the device maintains maximum physical compliance with modern functional safety specifications while drastically simplifying overall panel-mounting layout complexity.

Key Features

• Optimized Form Factor: Engineered for horizontal mounting directly below landscape-oriented multi-touch panels.
• High-Tactile Key Switches: Outfitted with robust RAFI RAFIX 22FS+ round 30 mm key switches for clear physical activation feedback.
• Integrated Status Annunciation: Every standard push-button houses an integrated signal lamp controllable over USB.
• Dedicated Physical Safety: Features 1 robust RAFI RAFIX 22FS+ emergency stop button with redundant safety contact pathways.
• Dual-Path Communication: Standard keys communicate via both USB (1 switch contact and LED driver) and a hardwired 19-pin circular connector for absolute signal flexibility.
• Custom Labeling System: Designed with insert-slot paths for direct push-button cap labeling to permit custom, application-specific designations.

Applications

• Automotive Assembly Lines: Localized manual control stations requiring direct physical emergency stop interaction.
• Heavy Machinery Control: Integration below multi-touch panels for continuous manual jog or homing sequences.
• Process Plant Visualization: Hardwired overrides for safety-critical valves or pump systems alongside dynamic graphical HMIs.
• Pharmaceutical and Cleanroom Panels: Robust IP-rated execution for operations where operators wear heavy protective gloves.

Technical Specifications

Connections and Interfaces

The C9900-G055 utilizes a highly dependable dual-channel connection layout designed to satisfy both non-critical HMIs and safety-critical hardware architectures.

Empirical Engineering Insights

Alternative Models & Compatibility

The C9900-G055 is physically custom-profiled only for landscape multi-touch panels. Ensure that you do not attempt to fit this extension to older single-touch panels or portrait-oriented systems, as the physical alignment brackets and polyurethane sealing profiles do not align. For portrait models, refer to the corresponding vertical extension suffix configurations.

Application Pitfalls & Engineering Notes

When routing signals in safety-critical systems, always avoid driving the emergency stop loop through the USB path. The USB connection is strictly for non-safety HMI feedback (signal lamp status and operator status push-buttons). The physical NC safety loops must run directly through the 19-pin round connector directly to certified safety relays or safety PLC inputs (such as Beckhoff TwinSAFE EL6900 terminals).

Commissioning & Wiring Tips

To guarantee the IP65 ingress rating of the panel assembly after mechanical connection, make sure the custom gasket interface is perfectly flat and free of twist before tightening the connection screws. Torque the mechanical mounting screws systematically from the center outward to ensure uniform pressure across the rubber seal.

Installation Guidelines

1. 1

   Carefully clean and verify the integration sealing surfaces on the underside of the landscape multi-touch panel and the top of the C9900-G055 housing.

2. 2

   Position the polyurethane gasket evenly within the specialized channel. Do not stretch or cut the gasket during fitting.

3. 3

   Mechanically mate the push-button extension to the panel chassis base, securing the internal hex screws to the recommended OEM mounting torque specifications.

4. 4

   Attach the 19-pin circular cable, locking the collar down securely to preserve the IP rating, then plug the auxiliary USB bus connection directly into the host panel PC controller port.
