This industrial-grade push-button extension facilitates direct tactile control alongside standard HMI visualization screens, making it ideal for machinery requiring immediate operator intervention. \n\nThe unit features 16 integrated push-buttons with signal lamps and a dedicated emergency stop button. To ensure high system reliability and safety compliance, the module utilizes a dual-contact architecture. Primary control signals and lamp states are transmitted digitally via CP-Link or USB, while secondary contacts and safety-critical circuits are routed to a terminal block for direct hardwiring.\n\n### Features\n* **Right-Side Mounting:** Engineered specifically for CP6x31-00xx and CP7x31-00xx 15-inch display panels without integrated keyboards.\n* **Tactile Operator Controls:** Equipped with 16 Siemens Signum square (30 x 30 mm) push-buttons featuring integrated signal lamps.\n* **Dedicated Safety Interface:** Includes 1 Siemens Signum emergency stop key designed for direct, hardwired safety circuit integration.\n* **Dual-Contact Architecture:** Each push-button features a primary normally-open (NO) contact transmitted via CP-Link\/USB and a secondary NO contact wired directly to an internal terminal row.\n* **Customizable Labeling:** Push-button caps support insertable labels for clear, application-specific function marking.\n* **Independent Lamp Control:** Signal lamps are driven directly via the CP-Link or USB interface.\n\n### Applications\n* Machine tool control stations\n* Automotive assembly and welding lines\n* Process plant visualization panels\n* Custom OEM machinery control consoles\n\n### Technical Specifications\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003cth\u003eParameter\u003c\/th\u003e\n    \u003cth\u003eValue\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eManufacturer\u003c\/td\u003e\n    \u003ctd\u003eBeckhoff\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003ePart Number\/Model\u003c\/td\u003e\n    \u003ctd\u003eC9900-E818\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eCompatible Series\u003c\/td\u003e\n    \u003ctd\u003eCP6x31-00xx, CP7x31-00xx (15-inch displays)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eMounting Location\u003c\/td\u003e\n    \u003ctd\u003eRight side of Control Panel \/ Panel PC\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003ePush-Button Quantity\u003c\/td\u003e\n    \u003ctd\u003e16 x Siemens Signum square (30 x 30 mm)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eEmergency Stop\u003c\/td\u003e\n    \u003ctd\u003e1 x Siemens Signum (directly wireable)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eContact Configuration\u003c\/td\u003e\n    \u003ctd\u003eDual Normally Open (NO) contacts per push-button\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eCommunication Interface\u003c\/td\u003e\n    \u003ctd\u003eCP-Link or USB (for primary contacts and signal lamps)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eHardwiring Interface\u003c\/td\u003e\n    \u003ctd\u003eTerminal row (for secondary contacts and emergency stop)\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eShipping Weight\u003c\/td\u003e\n    \u003ctd\u003e5 kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n### Connections and Interfaces\n\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003cth\u003eInterface \/ Connection\u003c\/th\u003e\n    \u003cth\u003eFunction\u003c\/th\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eCP-Link \/ USB Connection\u003c\/td\u003e\n    \u003ctd\u003eTransmits primary NO contact states and controls all integrated signal lamps.\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eInternal Terminal Row\u003c\/td\u003e\n    \u003ctd\u003eProvides direct hardwiring access for secondary NO contacts of all 16 push-buttons.\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eEmergency Stop Terminals\u003c\/td\u003e\n    \u003ctd\u003eDedicated hardwired terminals for integration into external safety relays or fail-safe controllers.\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n### Installation Guidelines\n* **Mechanical Mounting:** Secure the extension housing to the right side of the compatible 15-inch Beckhoff Control Panel using the provided mounting hardware. Ensure the gasket is properly seated to maintain the panel's environmental rating.\n* **Wiring Routing:** Route the USB or CP-Link communication cable away from high-voltage AC power lines or variable frequency drive (VFD) cables to prevent electromagnetic interference.\n* **Safety Circuitry:** The emergency stop button must be wired directly to a certified safety monitoring relay or fail-safe PLC input using the dedicated terminal row. Do not route safety-critical stop signals through the USB or CP-Link communication bus.\n* **Grounding:** Ensure the push-button extension housing is properly bonded to the common functional ground of the main control panel assembly.","brand":"BECKHOFF","offers":[{"title":"Default Title","offer_id":53106424545643,"sku":"C9900-E818","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/c9900-e818-bjxvqhippqp.png?v=1776243620","url":"https:\/\/www.plcprotech.com\/pt\/products\/beckhoff-c9900-e818-cp6xxx-and-cp7xxx-push-button-extension","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
