:
Isolated exposure output with photo coupler
(
Transistor NPN output
)
・
Use as open collector output. The sink current which flows into a camera should not exceed 50 mA. (Max
25V)
・
Due to the delay of a photo coupler, several
μ
s are delayed against the actual sensor exposure timing.
・
When a pull up resistor is used, the delay time is subject to fluctuate due to a pull up voltage, a pull up
resistor and a connecting circuit of user’s circuit. Need to set up a value to become an appropriate waveform.
