Notes on Parallel Input
•
To prevent input signal chattering, use a non-contact input (transistor etc.). If chattering occurs, inputs
may be missed or input recognition may be delayed.
•
Be careful when using only full-wave rectification (including ripples) power supply for DC input, as it
may cause abnormal operation.
•
Current leakage at the input side may not turn input off. In such as case, connect a resistor following
the figure below.
•
If Input to the LightPixAE20 is not turned off due to current leakage when 2-line photoelectric sensor (or
proximity sensor) is used, connect a bleeder resistor.
•
Even in cases where in-line LEDs such as LED reed switches are connected with an input contact
point, Voltage more than the ON voltage must be applied to the LightPixAE20 input terminal.
