I want to switch on/off some AC device using solid state Omron G3MB relay I know that for magnetic relay there should be transistor and flyback diode, but what about SSR? Can I connect it directly to arduino digital pin without any transistors and anything else?

In a closer look on special arduino module, we can see some extras. Are they necessary? I want to put solid state relay (not separated module) into my custom PCB, and I'm confused about that extras.
