Beckhoff C9900-G057 Push-Button Extension for CP39xx and CP32xx/CP37xx Panel PCs

Description

Engineered for direct mechanical integration with landscape-format multi-touch control devices, the Beckhoff C9900-G057 provides a tactical operator control interface for CP39xx Control Panels as well as CP32xx-1600 and CP37xx-1600 Panel PCs. Mounted horizontally below the main display unit, this heavy-duty expansion module delivers robust physical control elements directly to the machine-level interface. The inclusion of high-integrity physical keys, alongside an integrated emergency stop circuit, ensures high-reliability operator command input and compliance with equipment-level safety architectures.

Key Features

• Premium Key Switch Hardware: Utilizes heavy-duty, round 30 mm RAFI RAFIX 22FS+ push-buttons equipped with integrated signal lamps.
• Dedicated Safety Actuator: Features one centralized, high-visibility RAFI RAFIX 22FS+ emergency stop button with force-guided break contacts.
• Customizable Labeling: Includes insertable labels for individual button caps, allowing on-site custom configuration and clear operational marking.
• Dual-Channel Interface Paths: Flexible layout enabling switch contacts to communicate independently via USB or routed through a centralized 19-pin round connector.
• Ruggedized Industrial Housing: Designed to attach seamlessly to mounting-arm compatible multi-touch panels, matching their industrial IP-rating and mechanical profiles.

Applications

• Automotive assembly lines and robotic work cell master control stations.
• Machine tool control consoles requiring dedicated, physical cycle-start and emergency-stop mechanisms.
• Packaging and material handling environments requiring high-tactility operator inputs.

Empirical Engineering Insights

Alternative Models & Compatibility

The C9900-G057 is specifically dimensioned for the landscape-oriented physical configurations of the CP39xx, CP32xx-1600, and CP37xx-1600 form factors. It cannot be retrofitted to portrait variants or older-generation single-touch panels without substantial structural customization and loss of housing IP-integrity. Always verify the physical width matching of your specific monitor model prior to installation.

Application Pitfalls & Engineering Notes

When utilizing the USB channel for signal lamp status feedback and secondary key switch tracking, ensure your PC operating system is configured to prevent USB selective suspend power-saving modes. If the host operating system puts the USB root hub to sleep, LED indications and non-hardwired key presses will experience communication dropouts. Safety-related emergency stop contacts must remain hardwired directly through the 19-pin interface to your safety controller or safety relay.

Commissioning & Wiring Tips

To guarantee electromagnetic compatibility, the 19-pin round cable assembly must be fully shielded, with the shield terminated directly to the connector shell. Ensure the panel PC and push-button extension housing are commonly grounded through the mounting arm mechanism. Grounding straps should bridge the physical joint between the extension housing and the multi-touch panel to minimize transient potential differences.
