Characteristics
7.3.1
Input
Signal:
Each input signal is connected to the LED (cathode side) of the photo-coupler. The LED
(anode side) is connected to the pull-up power supply voltage.
7.3.2
Output
Signal:
Each output signal is outputted via a pull-up 5k
Ω
(0.1W) resistor by using Darlington
Transistor to provide high-current and high-voltage level translation.
7.3.3
Power
supply
The power supply for the judgment output signal pull-up and that for the operation
output signal pull-up and input signal drive can be set separately. You can select from
+3.3V to +35V external power supply.
An internal VCC (5V DC) has been supplied for testing purpose.
To use the internal power, please connect PIN-34 and PIN-35 together.
