@neilgl, just Google for "single relay optocoupler schematic" and there are a few to look at.
I wasn't looking for an exact match -- I wanted to check whether there is a resistor in series at the opto input side. Your board schematics should be broadly similar. Also gmx's pix shows the diode for the coil -- the black 2-pin sod part, so well, the board looks fine as long as the jumper settings are correct.
I think I still want to blame the DC motor for the glitch...
