I need an off-the-shelf board with a lot of relays, maybe 26 relays minumum. Most of the relay boards I've found have connector interfaces to hookup with a specific "thing" that the manufacturer of the relay board makes. For example, Advantech or Omega have relay boards, but they are not laid out generically. Do you have any suggestions?
I'm not too picky on the drive circuit for the relays (ULN chip, transistors, fets, whatever).
