MODEL FL230 VOLTAGE TO FREQUENCY CONVERTER

MODEL FL230 VOLTAGE TO FREQUENCY CONVERTER

Description
The Model FL230 is a voltage-controlled oscillator, producing 0-5V output pulses at a frequency proportional to a voltage or current input signal.  Accuracy is within ±0.25% from 5% to 110% of full-scale input.  The FL230-005 features an operating range is -0.6V to +3.4V, allowing for operation at zero volts input signal.  The full-scale output frequency can be factory-set for any desired range up to 50kHz.

Specifications
