Pepperl & Fuchs – KFU8‑DW‑1.D (190149) – Rotation & Speed Monitor, SIL 2 Signal
The Pepperl & Fuchs KFU8‑DW‑1.D (P/N 190149) is a precision rotation/speed monitor and signal conditioner designed for industrial automation and safety applications. It accepts signals from proximity sensors, encoders, or NAMUR contacts and converts them into configurable relay outputs and analog/digital signals with user-defined thresholds, timers, and fault detection—perfect for overspeed/underspeed monitoring up to 40 kHz.
