You can use L1A and L2A for your 120VAC. The open and close signals are as follows. DO10 has to be a ground type signal, same for nudging, which is DO4 0n the 104 Board. The close DO7 is an input and needs yo be 120VAC. I am assuming the the inputs are 120V and not the 24VAC type, something to check before you start.So you L2A for any inputs and L1A for any outputs.
