Pepperl Fuchs KFU8-UFT-Ex2.D Frequency Converter (231202)

P&F KFU8-UFT-Ex2.D is a versatile 2-channel isolated barrier designed for hazardous area applications requiring frequency monitoring, slip detection, rotation direction evaluation, and synchronization checks. Supporting both NAMUR sensors and dry contacts, this unit offers current output, relay signaling, and passive transistor outputs. It can be programmed via PACTware™ or the onboard keypad and features built-in line fault detection (LFD) for safe and reliable operation in SIL 2 environments.
