Selection Notes

The 4 safety inputs and PROFIsafe interface separate this panel from the standard KP8/KP32 PN line: the 2x SIL 3 or 4x SIL 2 emergency-stop wiring lets an emergency-stop button on this panel feed a fail-safe CPU directly, without a separate safety relay in the cabinet. With 32 keys against the KP8 PN's 8, pick this panel when the station needs a full operator keypad plus safety inputs on one PROFINET drop rather than a small jog/select panel.

Applications

The aluminum front, IP65 rating, and mounting-clip installation suit this panel for machine control desks that combine standard push-button functions with an integrated emergency-stop circuit, cutting the wiring compared to a discrete pushbutton enclosure feeding a separate safety module.
