Pepperl+Fuchs KFU8-UFC-1.D Frequency Converter with Trip Values for NAMUR Sensors, Speed Monitoring and 0/4-20 mA Output

The Pepperl+Fuchs KFU8-UFC-1.D is a one-channel frequency converter with trip values for industrial signal conditioning and monitoring. Identified by Pepperl+Fuchs part number 231195, the unit converts a digital frequency input into a proportional analog current signal while also providing configurable switching and alarm functions.

Flexible input and output functions

According to Pepperl+Fuchs product information, the KFU8-UFC-1.D accepts inputs from two-wire or three-wire sensors, NAMUR sensors, and dry contacts. Its measuring range extends from 0.001 Hz to 10 kHz. The frequency value can be converted to a freely adjustable 0–20 mA or 4–20 mA output, allowing the signal to be transferred to a control, indication, or data-acquisition system.

The device also provides two relay outputs and one passive electronic transistor output. These outputs can be configured for functions such as minimum or maximum trip alarms, pulse division, fault signaling, or other application-specific switching tasks. Line fault detection helps identify problems in the connected field circuit and provides a useful diagnostic indication for maintenance personnel.

Configuration and installation

Users can configure the KFU8-UFC-1.D from the front control panel or through PACTware software. The front display and status LEDs support commissioning and operational checks by showing power, input activity, output state, and fault information. The unit uses screw terminals and mounts on a standard 35 mm DIN rail, making it suitable for installation in industrial control cabinets.

This combination of frequency conversion, analog transmission, trip monitoring, and fault indication can reduce the number of separate interface components required in a panel. It also gives technicians a centralized point for checking sensor pulses and configured alarm behavior during commissioning or maintenance.

Important checks before ordering

Industrial buyers should verify the complete model and part number before purchasing. Similar Pepperl+Fuchs frequency converters may differ in channel count, hazardous-area interface, power supply, output arrangement, functional safety approval, or configuration. For this item, confirm model KFU8-UFC-1.D and part number 231195 against the original device label and project documentation.

A quotation request should include the required quantity, input sensor type, frequency range, output signal, trip functions, supply voltage, installation environment, certification requirements, destination, and preferred condition. For replacement projects, clear photographs of the front panel, side label, terminals, and existing wiring can help reduce identification errors.
