Product Description

Description

The BECKHOFF C9900-E783 is an operator push-button extension designed specifically for integration with BECKHOFF CP6xxx and CP7xxx Control Panels and Panel PCs. Engineered to mount directly below compatible 15-inch display units that do not feature built-in keyboards, this hardware extension expands your operator interface by combining tactical physical controls with touch-screen operation.

This push-button extension provides operators with tactile controls for immediate action, including standard push-buttons, an integrated emergency stop button, a rotary Gray code selector switch, and front-accessible USB ports. By dividing input paths between USB transmission and direct physical wiring, the unit offers both simplified installation and high-reliability connection architectures for critical commands.

As part of its official lifecycle service phase, the BECKHOFF C9900-E783 is a critical replacement and retrofit component for legacy machine tools, processing plants, and existing factory automation setups requiring precise physical operator feedback interfaces.

Features

  • Specifically designed to fit below 15-inch BECKHOFF displays without integrated keyboards.
  • Features 16 square push-button keys (30 x 30 mm) equipped with integrated indicator lights.
  • Includes 1 heavy-duty, directly wireable emergency stop button for safety circuit integration.
  • Equipped with a 23-position Gray code selector switch monitored via the USB interface.
  • Dual-port USB Type-A interface located on the front panel, protected by an IP65 screw cap.
  • Flexible wiring options featuring USB transmission for standard signals alongside a secondary, direct-wire terminal row for redundant or high-reliability physical wiring.

Applications

  • Direct mounting below 15-inch BECKHOFF CP6942 and CP7942 Control Panels.
  • Direct integration with BECKHOFF CP6242, CP6442, CP6542, and CP7242 Panel PCs.
  • Machine tool operator panels requiring physical push-button controls alongside touch screens.
  • Legacy hardware replacements and retrofits for systems currently in active operational service.

Installation Guidelines

  1. Ensure that all electrical power to the host CP6xxx or CP7xxx Control Panel or Panel PC is completely disconnected before mounting.
  2. Verify that the physical housing dimensions of the 15-inch host unit align correctly with the mounting pattern of the C9900-E783 extension block.
  3. Securely mount the push-button extension below the display screen assembly using the specified mechanical fasteners.
  4. Connect the internal USB interface cable from the extension block to the designated USB host port on the Panel PC or Control Panel.
  5. Route and wire the physical emergency stop contacts to your machine's primary safety control relays or TwinSAFE systems.
  6. If direct physical feedback is required, connect the secondary normally-open (NO) push-button signal paths from the terminal row to your PLC input terminals.
  7. Verify that the IP65 screw cap is tightly secured over the front USB ports if they are not actively in use.
  8. Restore system power and test button states, lamp illumination, and the selector switch via your control software.
