thanks everyone for replying, and i am familiar with automation direct. that is what i am using right now. the problem is the size. I have the pcb to replace a plc, and it is a fraction of the cost and size for my project. now that that is done, the contactor is the largest component left and I want it to be smaller, thereby leading me to "triacs" which seem very small in comparison and I could put it right on to the pcb. maybe a pcb mount relay is the way to go here to save cost and size?
