Beckhoff C9900-E775 CP6xxx / CP7xxx Series Push-button Extension

Description

Designed for seamless mechanical and electrical integration with CP6x32-00xx and CP7x32-00xx series Control Panels and Panel PCs, the Beckhoff C9900-E775 push-button extension provides expanded operator control directly adjacent to the display. This right-side mounted extension module is optimized for 15-inch displays without integrated keyboards, delivering structured physical interface capabilities in harsh industrial environments.

The module features 18 high-durability, illuminated Siemens Signum square (30 x 30 mm) push-buttons alongside a dedicated Siemens Signum emergency stop switch. To ensure robust reliability, signaling is split into digital bus transmission and physical wiring options. Signal lamps are controlled through the primary communication channel, while the push-buttons support dual-channel operations for integration with legacy systems or high-safety hardware loops.

Features

• Specifically engineered for right-side mounting on Beckhoff CP6x32-00xx and CP7x32-00xx operator panels.
• 18 individual Siemens Signum square push-buttons (30 x 30 mm) with integrated signal lamps.
• 1 dedicated Siemens Signum emergency stop key, designed for direct hardwiring to safety relays.
• Dual-signal push-button transmission: one normally-open (NO) contact transmits via CP-Link or USB, while a second NO contact is accessible via a physical terminal row for direct wiring.
• Signal lamps operate exclusively through CP-Link or USB control interfaces.
• Customizable legend plates and labels for clear operator instruction and function marking.

Applications

• Industrial manufacturing execution systems (MES) and machine-level control panels.
• Power generation and heavy industry monitoring terminals.
• Automotive assembly lines requiring direct physical machine-stop interventions.

Installation Guidelines

• Ensure all system power is disconnected before initiating mechanical attachment of the extension.
• Align the mechanical connection points of the C9900-E775 with the right side of the host 15-inch Control Panel housing, tightening mounting screws to the specified torque.
• Wire the emergency stop switch directly to an approved safety evaluation relay or safety PLC using appropriate cable shielding.
• Connect the terminal row wiring for auxiliary hardwired NC/NO contacts where redundant signaling is required.
• Ensure the USB or CP-Link cable is correctly seated to facilitate signal transmission for the standard push-buttons and active lamps.
