It houses 18 individual push-button keys outfitted with integrated signal lamps (Siemens Signum square, 30 x 30 mm layout) and a dedicated Siemens Signum emergency stop key. Signal transmission is handled flexibly: primary button operations and all signal lamp controls are transmitted over CP-Link or USB. For safety-critical integrations and independent control loops, each push-button provides a second normally-open contact routed directly to an onboard terminal row for local hardwiring.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecifically designed for right-side mounting on Beckhoff CP6x32-00xx and CP7x32-00xx 15-inch displays.\u003c\/li\u003e\n  \u003cli\u003eEquipped with 18 Siemens Signum square (30 x 30 mm) push-buttons with built-in signal lamps.\u003c\/li\u003e\n  \u003cli\u003eIntegrated Siemens Signum emergency stop switch, designed for direct external hardwiring.\u003c\/li\u003e\n  \u003cli\u003eCustomizable label inserts under push-button caps to allow application-specific marking of control functions.\u003c\/li\u003e\n  \u003cli\u003eDual-channel connection capability: digital transmission via CP-Link\/USB alongside a local terminal row for direct wiring of secondary normally-open contacts.\u003c\/li\u003e\n  \u003cli\u003eSignal lamps operate exclusively through digital communication channels via the CP-Link or USB interface.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOperator panels on automotive assembly lines.\u003c\/li\u003e\n  \u003cli\u003eMachine-level HMI control stations in packaging and materials handling.\u003c\/li\u003e\n  \u003cli\u003eProcess control desks requiring physical emergency stop and manual cycle start\/stop overrides.\u003c\/li\u003e\n  \u003cli\u003eSpecialty machinery where software touchscreens are complemented by tactile operator controls.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eManufacturer\u003c\/strong\u003e\n      \u003ctd\u003eBECKHOFF\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003ePart Number \/ Model\u003c\/strong\u003e\n      \u003ctd\u003eC9900-E878\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eDevice Type\u003c\/strong\u003e\n      \u003ctd\u003ePush-button Extension\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eCompatibility\u003c\/strong\u003e\n      \u003ctd\u003eCP6x32-00xx and CP7x32-00xx (15-inch display without keyboard)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eMounting Side\u003c\/strong\u003e\n      \u003ctd\u003eRight side\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eControl Elements\u003c\/strong\u003e\n      \u003ctd\u003e18 push-buttons (Siemens Signum, square 30 x 30 mm) with signal lamps\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eEmergency Stop Element\u003c\/strong\u003e\n      \u003ctd\u003e1 Emergency Stop key (Siemens Signum), direct-wiring capable\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003ePrimary Interface\u003c\/strong\u003e\n      \u003ctd\u003eCP-Link or USB (for lamps and first normally-open contact)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eSecondary Interface\u003c\/strong\u003e\n      \u003ctd\u003eTerminal row for direct wiring of second normally-open contact\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eShipping Weight\u003c\/strong\u003e\n      \u003ctd\u003e5.0 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eConnections and Interfaces\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eInterface Type\u003c\/th\u003e\n      \u003cth\u003eFunction and Routing\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eCP-Link \/ USB Connection\u003c\/strong\u003e\n      \u003ctd\u003eTransmits primary push-button states (normally-open) and powers\/controls all signal lamps.\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eTerminal Row\u003c\/strong\u003e\n      \u003ctd\u003eProvides hardwired access to the secondary normally-open contacts for the 18 push-buttons.\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eE-Stop Terminals\u003c\/strong\u003e\n      \u003ctd\u003eDirectly wireable safety circuit interface for the Siemens Signum Emergency Stop key.\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Mechanically align and secure the extension unit to the right-hand chassis mounting points of the compatible 15-inch control panel.
