Original author: Monarch Instrument (source: https://monarchinstrument.com/products/f2a3x-frequency-to-analog-converter-tachometer)

## Components

- **WIZnet WIZ100SR** x 1 ([docs](https://docs.wiznet.io/Product/S2E-Module/WIZ100SR/))

## Article

## **DESCRIPTION**

The F2A3X Frequency to Analog Converter is a DIN rail module that converts a frequency input signal into a proportional analog voltage (0-5 V dc) or current (4-20 mA) output. The output signal is electrically isolated from the input signal and input power source, effectively eliminating troublesome ground loops. The input signal can be supplied from a Monarch sensor (measuring RPM for example) or any source of digital signal not exceeding 12 volts. The F2A3X is completely user-programmable using the [free downloadable** PM Remote Software**](https://monarchinstrument.com/pages/pm-remote-software). A NIST Traceable Certificate is included.

### **TYPICAL USES **

- Process monitoring over networks
