RLY10x and RLY20x TTL Relay Boards

Winford is transitioning to selling TTL relay boards that have some updates to their components. You can find more information about the differences in how these boards function in this document. In short, the RLY10x products will be discontinued and will transition to the RLY20x designs.

Notice that the previous models are now listed as "legacy". This simply means that these are models of the product that we won't be producing anymore; we don't recommend them for new designs. We'll still keep the pages active, though, in case you need any of the information, pictures, or documentation on them.
