Jarthel,
Every relay (almost) should have a diode across its coil. Sometimes, it can be confusing which way to place the diode... simple, place the diode so the diode does NOT conduct while the relay is "ON".

Hi Jarthel
Poobah is correct for mechanical relays as they can produce a high reverse voltage across the coil when the current is turned off. The diode absorbs this and prevents damage to other components.
However, this is a solid state relay and does not produce the inductive kickback so no diodes are necessary. You are only switching current through a LED.
Cheers
