Product Description

Description

Designed to expand hardware operator controls, the Beckhoff C9900-E935 is a high-reliability, right-side mounted push-button extension engineered specifically for 15-inch CP6xxx and CP7xxx Control Panels and Panel PCs lacking integrated keyboards. This rugged industrial human-machine interface accessory enhances machinery control by adding direct, tactile feedback devices alongside standard touch screens or displays.

The unit integrates industrial-grade control components, providing both digital bus-based signal transmission and hardwired auxiliary circuits. This dual-path connectivity guarantees that critical control signals can be integrated directly into physical safety networks while auxiliary signals run over standard USB links. With standardized mounting dimensions and robust physical button housings, it ensures seamless integration and longevity in demanding manufacturing environments.

Features

Specifically designed for right-side mounting on 15-inch CP6x13-00xx and CP7x13-00xx Control Panels and Panel PCs.
Features 20 industrial square push-button keys (30 x 30 mm, Siemens Signum style) with integrated signal lamps.
Includes 1 heavy-duty Siemens Signum emergency stop button, designed for direct wire-in safety circuits.
Supports customizable insert labels behind push-button caps for clear functional designation.
Dual-path signaling: Buttons transmit their primary normally-open (NO) contact state over USB, while a secondary normally-open contact is routed directly to a built-in terminal row for hardwired applications.
Feedback lighting: All integrated signal lamps are controlled and powered directly via the USB interface.

Applications

CNC machine tool operator panels.
Automotive assembly line HMIs.
Process control operator stations in power generation and chemical industries.
Specialty packaging machinery integration.

Internal Terminal Row	Provides direct hardwiring points for the second normally-open contacts of the 20 push-buttons.
E-Stop Terminals	Dedicated, hardwired connection terminals for integrating the Siemens Signum Emergency Stop button directly into safety circuits.

Installation Guidelines

Ensure that power to both the control panel and associated machine circuits is fully disconnected before beginning installation.
Mount the push-button extension to the right-side flange of the CP6xxx/CP7xxx panel using the original mechanical attachment points to maintain IP rating integrity.
Connect the USB interface cable directly to an active USB port on the host PC or controller. Do not use unpowered USB hubs.
Wire the auxiliary terminal block connections in compliance with local low-voltage control standards. Ensure appropriate shielding is applied to signal cables to prevent EM interference.
Always wire the emergency stop switch directly to an approved safety relay or safety PLC input. Do not process emergency safety signals through the USB data interface.

FAQ

Which Beckhoff control panels are compatible with the C9900-E935 extension?

The C9900-E935 is designed specifically for right-side installation on Beckhoff CP6xxx and CP7xxx series Control Panels and Panel PCs featuring a 15-inch display without an integrated keyboard, such as CP6x13-00xx and CP7x13-00xx.

How do the push-buttons communicate their status to the controller?

Each of the 20 push-buttons features a dual-path design. The first normally-open (NO) contact transmits state data digitally via USB, while a second independent normally-open contact is routed to a hardware terminal row for direct wiring to control inputs.

Can the integrated emergency stop button be monitored safely over the USB connection?

No. For industrial safety compliance, the Siemens Signum emergency stop button is not routed over USB. It must be hardwired directly to your machine's safety relay or safety controller using the dedicated terminal row.

How are the push-button signal lamps controlled?

All integrated signal lamps inside the push-buttons are powered and controlled strictly through the USB interface connecting the extension to the host Panel PC or terminal.
