1. opto isolator to turn on the output of the opto isolator goes low 0 volts and the signal is read as a low logic level binary 0 by the PC When the input signal is too low to turn on the opto isolator the output goes high and the port bit is read by the PC as a high logic level binary 1 The opto isolator requires approximately ImA to turn on The maximum input current is 50mA There are two things to consider when selecting the input resistor The first is turn on voltage for the circuit to sense and second is the maximum input voltage Maximum input voltage must not provide too much power to the input resistor and must also not overdrive the opto isolator input current specification The following formulas apply Turn on Voltage diode drop turn on current x resistance Ex 1 1 003 x R Input Current input voltage 1 1V resistor value Maximum voltage 1 1 square root of 25 resistor value The following table shows the ranges associated with the resistor Input Range Max Current TKO 5 30V Note The turn off voltage for all resistors is less than 1V i Because through hole resistors are utilized they cannot be easily replaced If modification is necessary Sealevel can do this for an additional charge Important The input circuits are not intended for monitoring 120 volt AC circuits In addition to being too high a voltage for the circuits it is dangerous to have that high a voltage on the2.
