I am trying to separately control several 24V solenoid valves to open and close in a timed fashion. In other words, I will need a computer program to control the valves individually based on a complicated, timed schedule. The computer program I have not looked for yet. The labjack U12 I have, and I have a CB25 interface for the D connections. I have no experience using these materials, nor do I have any advanced electronics knowledge. From other forum posts, I understand that I may need to use Solid State Relays and the D connections to accomplish my tasks. Could anyone explain how this may be done? Is it even possible to control up to 6 or 8 solenoid valves using one labjack connected to a laptop? I have one SSR - SNC R2025-507 and the solenoid valves are several different models. I am sorry to impose such simple questions upon the forums, but I searched google and still could not understand what I should do. Many thanks, Membrane Bioreactor Team

Have you looked at the PS12DC power switching board? Check out the datasheet below.

The PS12DC cannot be fit directly to a LabJack U12, but if you ran wires individually (like in the picture explaining how to connect it to an Arduino), that would work. I would recommend upgrading to a LabJack U3-LV though, if you have the money.

The alternative would be to purchase a bunch of solid state relays, and wire them individually to digital IO lines on the U12.
