Monarch Instruments F2A3X Signal Conditioner / Frequency to Analog Converter w/12-24 DCV Power, Communications & Alarms

F2A3X Series*

The Monarch Instruments F2A3X Frequency to Analog module converts a frequency input signal into a proportional analog voltage (0-5 DCV) or current (4-20 DCmA) output. The output signal is electrically isolated from 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. A NIST certificate of calibration is also included.
