12 volt opto relay single pole controller board converts digital or low voltage signals to solid state contact closures.

Ideal for adding to the Nayax VPOS Touch terminals to convert the Nayax signals to analog signals or contact closures. Connect +12V & the green signal wire from the Nayax. On the opposite end of the board with the resistor on the top connect the common to the center terminal and the nominally open to the lower screw lug as per the attached photo. Eliminates the possible bounce of the relay contacts of mechanical type relays.
