Mounted on the right-hand side of the operator unit, it expands standard panel capabilities with tactile, industrial-grade control hardware, allowing machine operators to execute rapid manual commands without relying solely on the touchscreen interface.\u003c\/p\u003e\n\u003cp\u003eEquipped with 16 square Siemens Signum illuminated push-buttons (30 x 30 mm) and one dedicated Siemens Signum emergency stop button, the C9900-E841 provides versatile signal integration. Each push-button transmits its primary normally-open (NO) contact digitally via USB or CP-Link to the host PC system, while all integrated indicator lamps are driven over the same digital bus interface. To accommodate critical interlocks and hardwired safety circuits, each push-button also provides an independent second normally-open contact accessible via an internal terminal strip, and the emergency stop button is directly wireable to external safety relays or TwinSAFE input terminals.\u003c\/p\u003e\n\u003cp\u003eThe C9900-E841 variant is engineered without a mounting arm connection and without an integrated cable bushing, making it suitable for panel assemblies where independent arm mounting is not required. External signal cabling can be routed using an optional screwed cable gland accessory (C9900-M931). The unit is classified in the BECKHOFF service phase for legacy maintenance, expansion, and direct system replacement.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRight-side enclosure extension engineered specifically for 15-inch display CP7702 and compatible CP6x02\/CP7x02 Control Panels and Panel PCs without keyboard.\u003c\/li\u003e\n  \u003cli\u003e16 Siemens Signum square push-buttons (30 x 30 mm) with integrated signal lamps.\u003c\/li\u003e\n  \u003cli\u003e1 Siemens Signum emergency stop button suitable for direct hardwiring into safety interlocks.\u003c\/li\u003e\n  \u003cli\u003eDual-circuit push-button architecture featuring digital transmission (USB or CP-Link) for one NO contact and direct terminal strip wiring for a second NO contact.\u003c\/li\u003e\n  \u003cli\u003ePush-button caps with insertable label areas to support custom machine function marking.\u003c\/li\u003e\n  \u003cli\u003eDelivered without mounting arm connection and without cable bushing for compact panel setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eParameter\u003c\/th\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eManufacturer\u003c\/td\u003e\n      \u003ctd\u003eBECKHOFF Automation\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExact Model\u003c\/td\u003e\n      \u003ctd\u003eC9900-E841\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Type\u003c\/td\u003e\n      \u003ctd\u003ePush-button extension\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eProduct Family\u003c\/td\u003e\n      \u003ctd\u003eIndustrial PC Control Panel Accessories (C9900 series)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCompatible Host Hardware\u003c\/td\u003e\n      \u003ctd\u003eCP7702-00xx (15-inch display, without keyboard);
