This hardware interface expansion is specifically designed for 15-inch displays without integrated keyboards, providing physical controls and safety functionality directly adjacent to the screen.\u003c\/p\u003e\n\n\u003cp\u003eThe extension features 18 illuminated square push-buttons and a dedicated emergency stop switch, providing tactile, high-reliability field input options. Communication for standard button states and lamp controls is handled via the host controller's CP-Link or USB connection. To ensure high-reliability integration with safety systems, the C9900-E975 supports a dual-contact architecture, offering both digital bus communication and direct, hardwired terminal connections.\u003c\/p\u003e\n\n\u003cp\u003eCurrently in its service phase, the \u003cstrong\u003eC9900-E975\u003c\/strong\u003e serves as an essential maintenance, replacement, or legacy expansion
