Description

Enlarge

With the Key Panels SIMATIC HMI KP8/KP8F PN Siemens offers a compact keypad operator panel designed for PROFINET environments at a favourable price.
Eight large and ergonomic keys, which can be illuminated in five different colors form a unit.
For larger control panels you can add further units without a gap and electrically connected due to integrated Ethernet switches as well as looped through 24 V DC.
For safety-related applications there is a failsafe variant KP8F PN.

Area of application

The rugged Key Panels are designed for simple and straightforward machine operation.They can be used wherever HMI functions cannot be carried out without keys and lamps, e.g. on control consoles for machines and plants .

Benefits

Design and functions

SIMATIC HMI KP8 PN offers 8 large illuminated pushbuttons which can easily be labeled with labelling strips. The keys feature tactile feedback. Thus they can be reliably operated even when wearing gloves. You can set five colors (blue, green, red, yellow, white) and the brightness of the keys via the STEP 7 hardware configuration. 8 I/O PINs are available on the rear side; these I/O PINs can be used to connect additional control elements.

The KP8F can be addressed by two controllers via the Shared Device PROFINET function.

The Key Panels can be installed next to each other without gaps, due to the integrated Ethernet switch the units can be part of a line topology and even the 24V DC can easily be looped through.

The format of the Key Panels is selected so that they are also ideally suited for installation into the expansion units of the fully enclosed HMI devices.  

Key Panel KP8F – the fail-safe version
With the help of the integrated PROFIsafe communication, this Key Panel can be used for fail-safe operation with SIMATIC S7-300F/400F. The two additional fail-safe inputs of the KP8F can be used for failsafe signals, e.g. sensors with floating contacts.
Two emergency stop buttons according to SIL 2 or one according to SIL3 can be connected.
