#SPS Key panels for use in tough and safety-related industrial applications

Two new key panels from the Siemens Industry Automation Division feature eight large, programmable keys with backlighting that can be adjusted in terms of brightness and color. The Simatic HMI KP8 and KP8F key panels are designed with IP65 protection at the front for tough industrial applications and are assembled ready for use, equipped with 2-port Profinet interface and integral switch and are easy to use with tactile feedback on operation of the keys. Simatic HMI KP8F is suitable for use in safety-related applications and also has two safety-related inputs for this purpose. In single-channel use, the safety integrity level SIL 2 is achieved, while in dual-channel use SIL 3 is attained.  Depending on the safety level, one or two emergency-off switches can be connected. Through the support of Profinet Shared Device, two controllers can be addressed simultaneously.

The new Simatic HMI KP8 and KP8F key panels are particularly suitable as a supplement to the Siemens HMI (Human Machine Interface) devices with all-round IP65 degree of protection, where they fit precisely into the expansion units and supplement the HMI devices with additional operating elements. The intensity of the LED backlighting of the new key panels can be adjusted individually to the ambient conditions, for example in difficult lighting conditions such as extreme brightness. The background colors are configurable in red, yellow, green, white or blue in order, for example, to signal different machine states. The user can even configure the individual keys, for example to alert the operator by flashing that interaction is required. All keys can be individually designated and adapted to the application by means of two labeling strips.

A typical application for key panels is the direct, deterministic transmission of operating commands. The new Siemens key panel is assembled ready for use, thereby eliminating the time-consuming individual assembly and wiring of conventional operator panels. Additional operating elements, such as pushbuttons, can be connected by means of eight programmable inputs/outputs mounted at the rear.
