Hello list members.
I´m looking for a DC to frequency converter that can convert the 4-20ma or 0-10VDC speed reference output of a VFD (or any similar analog signal, for the matter) to a pulse train of, for example, 0.1 to 10 Hz. This in order to monitor the VFD´s fequency by means of the digital inputs on my AB PLC-5, since I cannot install extra analog input modules (for cost, space, etc). Some of our VFDs do have pulse output signals, but most of them have only the analog signal.
I´ve looked at the Action AP7500 series, but would like to have other options.
Thanks in advance to all of you
Patrick
