3.4.3.1. Opto-Isolated Trigger Source
Figure 17 shows how an opto-isolated digital output of e.g. a camera can be connected to
trigger an IPSC. The opto-coupler of the trigger source should be able to supply at minimum
20mA current and be rated for minimum 24V voltage.
The shown pull down 1.2kΩ resistor should be rated for at least 0.5W power.
