Does this mean I could omit a current limiting resistor as the internal impedance would limit it to 3.3mA (5v/1500Ω=3.3mA)?
What does "Zero-crossing (resistive loads) or random-fire (inductive loads) output" mean?
I have also been reading that a snubber is not needed for SSRs. Will someone confirm or give argument otherwise?
Finally, is something like this safe to control directly from an output pin or should I use a transistor to switch it?
But anyways, I'm just rambling now...
