Extension de bouton-poussoir BECKHOFF pour écran 15 pouces C9900-K660

Overview

The C9900-K660  is a ruggedized industrial push-button extension designed by Beckhoff to augment the operational interface of CP6xxx and CP7xxx Control Panels and Panel PCs. Specifically tailored for 15-inch display variants without integrated keyboards, this extension module provides a tactile, hard-wired control layer essential for machine-side operations. Currently in its service phase, the C9900-K660 allows for the seamless integration of emergency stops, illuminated selectors, and momentary push-buttons directly beneath the visualization screen. By decoupling critical control commands from the touchscreen software layer, this module ensures high reliability for safety-relevant and frequently accessed manual functions in complex manufacturing environments.

Technical Configuration

The C9900-K660 is engineered for industrial-grade HMI (Human Machine Interface) enhancement:

• Display Compatibility: Exclusively optimized for Beckhoff 15-inch displays (landscape orientation).

• Tactile Control: Provides physical slots for industrial-grade push-buttons, allowing operators to execute commands without looking away from the process or relying on touch sensitivity.

• Integration: Designed to match the aesthetic and mechanical tolerances of the CP6xxx and CP7xxx series, maintaining the IP65 protection rating when correctly installed.

• Service Phase Status: As a service-phase component, it remains a critical spare part for maintaining existing installations in automotive, wood processing, and packaging industries.

Technical Specifications

Technical FAQs

Does this extension include the push-buttons pre-installed?

The C9900-K660 typically refers to the extension housing and internal wiring preparation. Specific push-button configurations (Emergency Stop, Start/Stop, etc.) are often customized based on the machine's specific functional requirements.

Can this module be retrofitted to an existing CP6xxx panel?

Yes, it is specifically designed to be added to panels that were originally ordered without a keyboard or button row, provided the mounting interface on the 15-inch chassis is available.

What is the significance of the "Service Phase" designation?

This means the product is no longer recommended for new machine designs but is fully supported for maintenance, repair, and replacement of existing units in the field.

Engineering & Installation Guide

Mechanical Attachment and Sealing

When attaching the C9900-K660 to a CP7xxx series panel, ensure the gasket between the display unit and the extension module is perfectly seated. Improper alignment can compromise the IP65 seal, leading to moisture or coolant ingress which can damage the internal terminal block and push-button contacts.

Wiring and Signal Logic

The internal wiring for Beckhoff push-button extensions often uses a common ground or individual digital inputs routed back to the PC via a dedicated internal interface or fieldbus (such as EtherCAT). Verify your panel's internal connection type (USB, hard-wired, or fieldbus) before final assembly to ensure the PLC successfully maps the physical button presses to the control logic.

Ergonomic Consideration

Install the extension such that the Emergency Stop button is unobstructed and within the primary reach zone of the operator. Since this module adds height to the overall HMI assembly, ensure the mounting arm or pedestal is adjusted to maintain a comfortable viewing angle for the 15-inch display.
