The Monarch F2A3X Signal Converter is a DIN-rail mounted unit that converts a frequency input signal into a proportional analog voltage (0-5 VDC) or current (4-20 mADC) 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 configurable over standard USB or optional Ethernet communications using the included PM Remote Software Package.

The Monarch F2A3X Signal Converter is particularly well suited for the following applications:

  • Process monitoring over networks
  • Tachometer signal generator
  • QC and R&D
  • Engine performance
  • Signal conditioning
  • Data acquisition
  • Motor or pump monitoring

Sensors are available as accessories. This unit uses sensors with tinned leads. When purchasing a sensor, please be sure to look at all product resources to ensure compatibility.
