BECKHOFF C9900-E527 Push-Button Extension

Description

The BECKHOFF C9900-E527 is a dedicated push-button extension designed for integration with industrial operator interfaces. It is built specifically to expand the physical control options of BECKHOFF CP6xxx and CP7xxx Control Panels and Panel PCs equipped with 19-inch displays that do not feature integrated keyboards, including CP6x03-00xx and CP7x03-00xx configurations. This accessory is currently in its service phase, making it highly relevant for the maintenance and modernization of existing control architectures.

For installation on the right side of the panel, the BECKHOFF C9900-E527 features 20 Siemens Signum square (30 x 30 mm) push-buttons, each equipped with an integrated signal lamp to provide immediate operational feedback. In addition, a dedicated Siemens Signum emergency stop key is incorporated directly into the panel layout to ensure a reliable safety interface. The push-button caps are designed with clear insertable labels, enabling customized operator marking for clear system navigation.

Engineered with dual-channel wiring flexibility, the push-buttons transmit their states to the controller via USB with a standard normally-open (NO) contact. For integration with hardware-based interlocks or safety systems, every push-button includes a second, independent normally-open contact that can be directly hardwired to external automation systems using a terminal row. All signal indicators and lamps are driven exclusively via the USB connection.

Features

• Engineered for mounting on the right side of CP6xxx and CP7xxx 19-inch displays.
• Features 20 square Siemens Signum push-buttons (30 x 30 mm) with integrated signal lamps.
• Includes 1 heavy-duty Siemens Signum emergency stop key.
• Dual-path signaling allows USB transmission (first NO contact) and direct wiring via an onboard terminal row (second NO contact).
• Indicator lights are controlled dynamically via the integrated USB interface.
• User-customizable keycaps allow simple insertion of printed labels.

Applications

• Operator control expansion for CP6xxx and CP7xxx series Control Panels and Panel PCs.
• Industrial visualization systems requiring discrete physical controls alongside a touch display.
• Standard machine control environments demanding hardwired emergency stop integration.
• Retrofitting and replacement of legacy 19-inch BECKHOFF operator terminals in service phases.

Installation Guidelines

1. Ensure the host control system is fully de-energized before mounting the extension.
2. Verify mechanical compatibility with the 19-inch BECKHOFF Control Panel (such as CP6x03-00xx or CP7x03-00xx series).
3. Align and secure the push-button extension to the right side of the control panel housing.
4. Connect the USB interface cable to the designated port on the Control Panel or Panel PC.
5. Wire the emergency stop button directly to your machinery's hardwired safety circuit.
6. If secondary signaling is required, wire the respective push-button contacts from the terminal row to your auxiliary system.
7. Power up the main unit and configure the USB control interface within the engineering environment.
