Someone else will have to handle the minimum contact time but I can address the 12V question. The EZIO2X4 has a +5V output, it does not have a +12V output. What you are seeing are the two opto-isolated inputs; I1-, I1+, I2-, I2+ (not 12+). The EZIO6I does have a +12V output, but does not have output devices (relays), like the EZIO2X4.
