The frequency indicator PCE-N24Z is used to display AC parameters. The built-in display can measure and display AC current, AC voltage or frequencies. The possibility of freely scaling the input signal allows a very versatile use of this built-in display. The current measurement result is very easy to read thanks to the large 4-digit LED display. The optional 24 V sensor supply allows direct connection of 2-wire sensors or transmitters, which simplifies the use of this process display. The configuration is carried out using the freely available software LPCon. With the help of the programming adapter PCE-PD14, settings can be made or read out from the built-in display. The configurations created with the software can be saved and called up again.
