Product Description

Description

The BECKHOFF C9900-E708 is a right-side push-button extension engineered for integration with CP6xxx and CP7xxx series Control Panels and Panel PCs. Specifically designed to match 15-inch display models without integrated keyboards, this auxiliary interface panel expands physical, tactile operator controls directly on the unit enclosure. It provides a structured arrangement of standard operating elements and an emergency stop switch to support direct machine interaction.

This extension features twelve square Siemens Signum push-buttons, each equipped with an integrated signal lamp, alongside a dedicated Siemens Signum emergency stop key. The C9900-E708 offers dual-transmission architecture: it transmits a single normally-open contact for each push-button via USB or CP-Link, while providing a second, independent normally-open contact wired directly to an internal terminal block. The integrated signal lamps operate exclusively via the digital CP-Link or USB communication channel.

Features

Designed for right-side mounting on 15-inch display CP6xxx and CP7xxx (including CP6x21-00xx and CP7x21-00xx) keyboardless Control Panels and Panel PCs.
Equipped with 12 square Siemens Signum push-buttons (30 x 30 mm) containing integrated status signal lamps.
Includes 1 Siemens Signum emergency stop key, designed for direct wiring into local safety circuits.
Dual-circuit contact transmission featuring one software-communicated contact and one hardwired terminal contact per standard button.
Removable push-button caps allowing insertion of custom labels for tailored function marking.
Optimized for systems operating under active service and maintenance lifecycles.

Applications

Tactile machine control and local status indication directly adjacent to the primary visual interface.
Hardwired emergency stop loop integration on industrial control operator arms.
Custom operator panel configurations requiring physical push-buttons and localized lamp feedback.

Installation Guidelines

Ensure all electrical power sources to the host CP6xxx or CP7xxx Control Panel and connected circuits are completely de-energized.
Verify that the push-button extension model matches the display size and configuration of your host control panel.
Mount the C9900-E708 extension securely to the right side of the control panel housing using the appropriate mounting hardware, ensuring proper alignment and environmental sealing.
Route and connect the internal USB or CP-Link interface cabling to the corresponding connectors on the host panel.
Wire the auxiliary terminal row for the secondary push-button contacts and the emergency stop circuit according to your machine's schematic diagrams.
Secure all electrical connections, re-apply power, and perform functional tests to verify button signals, status lamps, and emergency stop circuit safety loops.

FAQ

Which Control Panels is the BECKHOFF C9900-E708 compatible with?

The BECKHOFF C9900-E708 is designed specifically as a right-side push-button extension for 15-inch CP6xxx and CP7xxx series Control Panels and Panel PCs without an integrated keyboard, such as the CP6x21-00xx and CP7x21-00xx configurations.

How do the standard push-buttons on the BECKHOFF C9900-E708 transmit signals?

The BECKHOFF C9900-E708 uses a dual-circuit approach: one normally-open contact per button is transmitted digitally via USB or CP-Link, while a second normally-open contact is wired directly to an internal terminal block for conventional hardwired control.

Is the emergency stop button on the BECKHOFF C9900-E708 transmitted over USB or CP-Link?

No, the Siemens Signum emergency stop key on the BECKHOFF C9900-E708 is designed to be directly wireable to a hardwired safety circuit via its internal terminal contacts, operating independently of the digital interface.

How are the signal lamps on the BECKHOFF C9900-E708 controlled?

All 12 signal lamps integrated into the push-buttons of the BECKHOFF C9900-E708 are controlled exclusively via the digital CP-Link or USB communication interface and cannot be hardwired directly.

Can I customize the labeling on the BECKHOFF C9900-E708 buttons?

Yes, the BECKHOFF C9900-E708 features push-button caps designed to accept custom insertable labels, allowing users to define unique markings for each of the 12 operator keys.
