    Can anyone tell me what voltage will trigger this electronic relay?
    I have attached link to the spec sheet as a .pdf

    It is the item circled in red

    Hello,

    Did you read the datasheet?
    The input is an IR led that has a voltage drop of about 1.25 Volts.
    As it is an led you will need a current limiting resistor.

    The first result on google for "LED calculator" will tell you what resistor to use.
