AP7500 & AP7501 DC to Frequency Converter
Brand: EurothermThe AP7500 and AP7501 are useful in totalizing applications, where the total number of pulses counted in a given time period represents the time integral of the DC input.
The AP7500’s 6V square wave output can be used to drive electronic counters (DTL, TTL, CMOS).
The AP7501 can be used to drive electromechanical counters when connected to an external AC or DC power source.
The AP7500 can also be used in telemetry systems, where the dc signal is converted to a frequency, transmitted over long lines, and then decoded at the receiving end by means of a frequency to DC converter, such as the AP7380.
In the AP7501, the DPDT relay contacts are pulsed (closed) for only a short duration (100 Milliseconds) for compatibility with standard electromechanical counters.
