10.2 Electrical characteristics
Specifications for optocoupler are as follows:
Otherwise, external power source and series resistor are essential to input and output.
The optocoupler input triggers the tester by an input current of 10mA (maximum 30mA forward
and maximum 6V reverse).
The optocoupler outputs are rated 25V and 10mA each.
Bothe input and output require external power and series resistors (maximum 35V, 10mA).
Table 0-1 HANDLER signals
Bin result:
All /BIN (bin signal) outputs are collector ones.
External trigge r:
In EXT.TRIG mode, STB6684 is triggered by rising edge
impulse signals applied on the pin.
Voltage control:
In EXT.TRIG mode, STB6684 is triggered by rising edge
impulse signals applied on the pin. It is used to enable or
disable the voltage.
