The shrewd alternative to long-stroke keys
In the past, operator input to a machine was only rarely possible without permanently wired operator controls. Whether you were dealing with emergency stop, pushbuttons, switches, indicator lights, or key-operated switches: All these controls had to be planned, ordered, installed, wired, labeled and maintained. Their time-consuming and often error-prone individual installation constituted a significant cost item in control cabinet construction. Siemens proves that it can be done more efficiently and cost effectively – with SIMATIC HMI Key Panels.
Save on costs, not on functionality
The SIMATIC HMI Key Panels impress users by offering maximum flexibility in the most restricted space – and at an extremely favorable price. They also offer an abundance of other benefits
Significantly simpler …
With the SIMATIC HMI Key Panels, many basic functions can be combined to optimize costs, and the configuring and installation overhead can be reduced to a minimum. Compared to conventional installation, the use of a pre-assembled, ready-to-install key panel reduces the wiring overhead to a minimum
… faster …
... and more cost-effective
You also profit from significant savings in material costs. Integration into a key panel pays off, even from just three keys. Keys that are not required initially can be activated later at any time by configuring
Compact and rugged
Fast, space-saving attachment of the compact devices using clamps or a PRO empty enclosure – in the control cabinet as well as next to the machine.
Simply everything in view
The illuminated pushbuttons can be labeled individually and all have dimmable LED backlighting. In addition, process-controlled display of five colors (red, green, blue, white and yellow) is possible.
High availability and integral diagnostics
Faults can be bridged by means of an integral redundancy mechanism. A wire break or component failure, for example, can be offset by the Media Redundancy Protocol (MRP) for networks with a ring topology.
Safe data traffic with PROFINET
With two PROFINET-enabled Ethernet interfaces onboard and integral switch functionality, the KP8 PN can be integrated extremely easily into existing automation networks – without costly cabling or additional hardware.
24 V voltage supply can be looped through
The SIMATIC HMI Key Panels can be installed next to each other without gaps, and the 24 V voltage supply can be simply looped through from the neighboring panel.
With its integral safety functionality, the KP8F PN guarantees error-free transfer of safety-related signals via PROFIsafe. There are two fail-safe inputs for the connection of a SIL 3 emergency stop pushbutton, for example.
All Key Panels at a glance
SIMATIC HMI KP8 – the compact keypad operator panel
With the Key Panels SIMATIC HMI KP8 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.
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 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.
