Designed for demanding HMI environments, this industrial push-button extension complements host panels without integrated keyboards by adding physical buttons, safety-critical emergency stops, and visual feedback lamps. The unit supports dual-channel signal architecture, combining digital bus transmission (via CP-Link or USB) with direct-wire terminal connections to guarantee system interoperability and fail-safe hardware control.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;

For safety-critical status loops, the second NO hardware contact on the terminal block should be used to run a physical loopback to an isolated PLC input card, ensuring logic verification independent of the display link.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen wiring the direct-access terminal row, use a shielded control cable if routing paths are adjacent to variable frequency drives (VFDs) or three-phase power lines.
