PN101 Opto Synapse (Oscillator)


The Opto Synapse should be connected to the input of a Pop Neuron. These signal is a triangle wave.
It uses two optocoupler for controlling two output resistors. One has to trim the two potentiometer for an wide range of the output resistor. On poti is for the attenuation, the voltage should be peak to peak 6V. The second one rises the voltage level. The minimum voltage should be 3V. After triming the potis the signal that goes in the optocoupler should be between 3 and 9V.
