About 6AV3688-3EH47-0AX0 16 DI + 16 DI/DO and 4 fail-safe digital inputs, Front IP65, medial conformal coating for high-density fail-safe mechanical control in extreme environments

Maximize complex machine control and functional safety in harsh conditions with the ruggedized Siemens SIPLUS HMI KP32F PN Key Panel. Specially built on the hardware architecture of the standard high-density model (6AV3688-3EH47-0AX0), this hardened variation is fortified with an advanced polymeric conformal coating to safeguard internal electronics against moisture, condensation, and corrosive gases. It operates reliably within an expanded temperature window from -20 C up to +55 C, making it ideal for severe climate variations. The massive command layout hosts 32 heavy-duty short-stroke keys paired with 5-color parameterizable LEDs for instantaneous physical tracking on high-stress factory floors. Dual integrated PROFINET ports natively execute PROFIsafe protocols to seamlessly process up to 4 single-channel or 2 dual-channel safety loops directly from the machine interface. Complete with a versatile I/O footprint of 16 standard digital inputs, 16 configurable DI/DO channels, a loop-through 24V DC power structure, and a tight front IP65 protection rating, it delivers uncompromising tactile control under the most demanding manufacturing demands.
