Understand the difference.
Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.
V/F
SymbolsVoltage / frequency converter
Converts between an analogue voltage and a pulse-frequency representation in the documented selected configuration.
- Drawing use
- Schematic
- Application
- Logic & signals
- Reference family
- Manufacturer
A distinction that matters
The drawing must state the selected direction; the same component family may support V-to-F and F-to-V through different external connections.
Hz
SymbolsFrequency meter
A frequency meter indicates the frequency of its measured input. The source of that input must be clear when multiple buses or generators are present.
- Drawing use
- SLD / Schematic
- Application
- Metering & protection
- Reference family
- IEC / Manufacturer
A distinction that matters
A frequency meter displays a quantity; an underfrequency relay applies an operating threshold.
