My project ideally needs 6 relays. I noticed there is a 16 relay module, but that is too big to fit inside the Cobra ii enclosure. I think it’s a little over 7" whereas the enclosure is only a little over 5". Is this module my only option short of attaching 6 of the module x 1 modules?
Also, is there a module that will offer a high, med and low speed, like to control a fan for example?
