This extension module mounts directly to the right side of compatible 15-inch Beckhoff Control Panels and Panel PCs, specifically within the CP6x21-00xx and CP7x21-00xx series that do not feature an integrated keyboard. By combining digital bus communication with direct hardwired safety paths, the \u003cstrong\u003eC9900-E808\u003c\/strong\u003e provides operators with immediate physical feedback for critical machine functions while maintaining a clean, integrated panel aesthetic.\u003c\/p\u003e\n\n\u003cp\u003eThe unit features 12 square push-buttons with integrated signal lamps and a dedicated emergency stop button. To ensure high reliability and compliance with standard safety architectures, the module utilizes a dual-contact design. Primary control signals and lamp states are transmitted via CP-Link or USB interfaces, while secondary normally-open (NO) contacts and the emergency stop switch are routed to an internal terminal block for direct, fail-safe hardwiring to safety relays or PLC inputs.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for direct right-side mounting
