This rugged industrial human-machine interface accessory enhances machinery control by adding direct, tactile feedback devices alongside standard touch screens or displays.\u003c\/p\u003e\n\n\u003cp\u003eThe unit integrates industrial-grade control components, providing both digital bus-based signal transmission and hardwired auxiliary circuits. This dual-path connectivity guarantees that critical control signals can be integrated directly into physical safety networks while auxiliary signals run over standard USB links. With standardized mounting dimensions and robust physical button housings, it ensures seamless integration and longevity in demanding manufacturing environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecifically designed for right-side mounting on 15-inch CP6x13-00xx and CP7x13-00xx Control
