SIEMENS SIMATIC HMI KP8F

The SIMATIC HMI KP8F PN is a compact key panel featuring 8 short-stroke mechanical keys, multi-color LED illumination, and PROFINET connectivity. Designed for industrial automation applications, it provides intuitive machine operation while combining operator controls, configurable I/Os, and safety functions in a single device.

With 8 configurable digital I/Os, two integrated PROFINET ports, and a 24 V DC power supply with loop-through capability, the KP8F PN helps simplify wiring and installation. The F variant also supports fail-safe applications, including direct connection of safety signals such as Emergency Stop.

Key Features

• 8 large mechanical keys with clear tactile feedback for reliable operation.
• Multi-color LED illumination provides clear, language-independent status indication and remains visible in daylight.
• Two integrated PROFINET ports with built-in switch support line and ring topologies.
• Plug & Play design can reduce wiring and installation time by more than 60%.
• Material costs can be reduced by more than 30% compared with conventional keypad operator panels.
• 8 configurable digital I/Os are available on the rear for connecting switches, indicator lights, sensors, and other devices.
• Fail-safe inputs support safety signals such as Emergency Stop in SIL 2/3 applications.
• Compatible with standard PROFINET master CPUs, including non-Siemens controllers.
• Flexible parameterization allows the panel to be adapted to different machine requirements.
• Blank front versions provide space for additional 22.5 mm standard operator controls.
• IP65 installation enclosure options are available for suitable applications.

Benefits

The KP8F PN combines multiple functions in one compact operator panel, helping reduce the complexity of machine installation and control systems.

• Less planning and assembly effort compared with using separate components.
• PROFINET connectivity, I/O functions, and operator controls are integrated into one device.
• Digital I/Os can be configured according to the requirements of the application.
• Key colors can be dynamically adjusted to represent different process conditions.
• Keys and indicators can be labeled using a standard printer, including black-and-white or color printing.
• Integrated diagnostics support easier monitoring and troubleshooting.
• The blank front design allows space to be reserved for future system expansion.
• Standard 22.5 mm switches and pushbuttons can be installed without complex panel modifications.
• The F variant provides SIL 2/3 safety functionality, allowing safety devices such as Emergency Stop buttons to be connected directly.

Applications

The SIMATIC HMI KP8F PN is suitable for a wide range of industrial applications, including:

• Automotive
• Food & Beverage
• Oil & Gas
• Machine Building
• Industrial Automation
• Special-purpose machine manufacturing

Its rugged and easy-to-clean front makes it suitable for demanding industrial environments. The illuminated keys provide clear visual feedback, while the compact design allows the panel to be integrated into different machine configurations with minimal wiring.

Design & Installation

Blank Front Design

The blank front version offers additional flexibility for customized operator panels.
