Specifically engineered to match units with 15-inch displays without integrated keyboards, this unit expands digital operator interfaces with physical controls, status indications, and safety elements. It provides an ergonomic interface to transition software actions into direct mechanical feedback on the machine floor.\u003c\/p\u003e\n\u003cp\u003eThis extension features 20 square push-button keys with integrated signal lamps and a dedicated emergency stop button. System integration uses a dual-path communication topology. Primary button activations and signal lamp controls are handled over a USB connection, while a secondary independent wiring path is provided for physical control and safety logic integration. Each push-button contains a second normally-open contact mapped directly to a local terminal block for direct-wire system configurations.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eEngineered for right-side mounting on compatible 15-inch display Control Panels and Panel
