WebSep 2, 2016 · Optocoupler is just one more step of precaution. You can remove the optocoupler and power the coils using those 4 transistors by directly connecting the bases to Raspberry Pi (via resistors surely!). But make sure that you have a good 5V supply. Some 5V Relays just fail to turn on with low voltages as low as 4.2V. WebAug 28, 2013 · You are allowed to run the current from the camera through the transistor side of the optocoupler. Just be sure the polarity is right. Measure the pins for "shutter" and see which one is positive. Positive from the camera goes to pin 4 and the less positive voltage from the camera on pin 3.
