This push-button extension unit streamlines field operations by placing physical control elements directly adjacent to the visualization interface, facilitating rapid and tactile operator response in complex manufacturing environments.\u003c\/p\u003e\n\n\u003cp\u003eThe unit features 12 square Siemens Signum push-buttons equipped with integrated signal lamps, allowing for both input command and status feedback. For safety-critical functions, a dedicated Siemens Signum emergency stop button is mounted on the assembly. Signal transmission is highly flexible: all standard push-buttons feature dual-contact capabilities, allowing primary commands to travel via digital CP-Link or USB interfaces while simultaneously supporting direct wiring of a secondary normally-open (NO) contact via an integrated terminal row. The integrated emergency stop key bypasses interface electronics and is designed strictly for direct, hardwired integration into the system safety circuit.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRight-Hand Panel Mounting:\u003c\/strong\u003e Engineered specifically for mounting on the right side of compatible 15-inch Beckhoff Panel PCs and Control Panels.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTactile Operator Interface:\u003c\/strong\u003e Features 12 Siemens Signum square (30 x 30 mm) push-buttons with integrated status indicator lamps.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSafety Integration:\u003c\/strong\u003e Includes 1 Siemens Signum emergency stop button designed for direct wiring to safety relays or fail-safe controllers.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-Channel Transmission:\u003c\/strong\u003e Supports simultaneous digital transmission (via CP-Link or USB) and hardwired terminal connection for push-button contacts.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCustomizable Labeling:\u003c\/strong\u003e Clear, removable caps on the push-buttons allow for easy insertion of custom labels and functional designations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMachine tool control stations requiring physical override switches.\u003c\/li\u003e\n  \u003cli\u003eAutomotive assembly lines utilizing 15-inch Panel PCs.\u003c\/li\u003e\n  \u003cli\u003eHeavy industrial environments demanding redundant physical and digital control paths.\u003c\/li\u003e\n  \u003cli\u003eProcess manufacturing systems with localized safety circuit requirements.\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 Automation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003ePart Number \/ Model\u003c\/strong\u003e\n      \u003ctd\u003eC9900-E905\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eCompatibility\u003c\/strong\u003e\n      \u003ctd\u003eCP6x21-00xx and CP7x21-00xx 15-inch Control Panels \/ Panel PCs (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\u003ePush-Buttons\u003c\/strong\u003e\n      \u003ctd\u003e12 x Siemens Signum square push-buttons (30 x 30 mm) with indicator lamps\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eEmergency Stop\u003c\/strong\u003e\n      \u003ctd\u003e1 x Siemens Signum emergency stop button (directly wireable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003cstrong\u003eSignal Transmission (Push-buttons)\u003c\/strong\u003e\n      \u003ctd\u003eCP-Link or USB (1st NO contact);
