Description
The F2A3X Frequency to Analog Converter is a DIN rail module that converts a frequency input signal into a proportional analog voltage (0-5Vdc) or current (4-20mA) 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 Monarch sensor (measuring RPM for example) or any source of digital signal not exceeding 12 volts. The F2A3X is completely user programmable using the included PM Remote Software. A NIST certificate of calibration is included.
