Siemens 6AV3688-4EY06-0AA0 Push Button Panel 32 Keys

Siemens 6AV3688-4EY06-0AA0 Push Button Panel PP17-II PN is a 32-key operator input module for SIMATIC HMI systems that is PROFINET-capable. The unit provides 32 short-stroke push buttons and 32 surface LEDs configured on the PP17-II front face, delivering tactile control plus per-key visual feedback. It includes 16 digital inputs and 16 digital outputs to connect with PLC logic and device signals, enabling direct integration into control panels without additional interface hardware. Identified by the 6AV3688-4EY06-0AA0 code, this PP17-II PN push button panel is designed for Siemens automation architectures and is specified as part of the PP17-II family with PROFINET communication. With 32 independent keys, operators can trigger dedicated functions, switch modes, or provide status feedback, while the 32 LEDs support at-a-glance indication of active states or responses from the controller. This panel is suitable for machine-level control stations and other industrial environments where compact, high-density input and visual feedback are required, aligning with Siemens' SIMATIC HMI and PROFINET ecosystems.
