Siemens 6AV3688-4EY06-0AA0 Push Button Panel PP17-II

Siemens 6AV3688-4EY06-0AA0 Push Button Panel PP17-II is a SIMATIC operator panel designed for direct local control in PROFINET-enabled automation. The unit provides 32 short-stroke pushbuttons with 32 surface LEDs for per-button status indication and packs 16 digital inputs and 16 digital outputs, enabling direct signaling and feedback without additional I/O modules. It includes a PROFINET interface with two ports and requires a 24 V DC power supply, making it suitable for compact control cabinets alongside SIMATIC controllers. Identified by the part number 6AV3688-4EY06-0AA0, this PP17-II PN configuration supports mapping user actions to configured I/O and uses the built-in LEDs to convey operational states. This device belongs to Siemens' SIMATIC HMI family and is intended for industrial environments where robust operator interaction and networked control are needed. The PP17-II arrangement is commonly described as 32 keys, 32 LEDs, and 16 DI/16 DO with PROFINET, reinforcing its role as a compact, networked control panel for machine automation.
