Siemens 6AV3688-3AY36-0AX0 SIMATIC HMI KP8 PN Key Panel 8 Keys PROFINET HMI Operator Panel

The Siemens 6AV3688-3AY36-0AX0 SIMATIC HMI KP8 PN is a key panel with 8 short-stroke switches and multicolor LEDs, offering 8 configurable digital I/O pins over two PROFINET interfaces with an integrated switch. It runs on 24 V DC that can be looped through the connector without interruption, and it carries an IP65 front rating for panel-mount machine control.

Selection Notes

The 8-key count and 8 direct S7 I/O pins fit machine stations that need a compact operator interface without a full graphic HMI screen for example start/stop, jog, and mode-select buttons wired straight into the PLC over PROFINET. Because the two PROFINET ports include a built-in switch, the KP8 PN can sit in a line or ring topology without an external switch, which simplifies cabinet wiring versus a panel that needs its own network hardware. Choose the larger KP32F PN key panel instead when the application needs more than 8 keys or PROFIsafe-rated safety inputs.

Applications

Clamp-terminal mounting and the IP65 front rating suit this panel for direct front-of-cabinet or machine-frame installation in wash-down or dusty production areas, while ATEX Zone 2/22 and cULus Class I Division 2 markings on the family extend use to hazardous-area machine control stations.
