I wince when I read about the 24 volt solenoids. In the real world, this would be considered a very bad design decision.
The 24-volt supply provides stable power to the controlling computer. Attaching switched coils to this supply guarantees that transients will occur during operation. Although the crio has protection agains damage, there is the risk of program interruption. In the worst case, the controller would have memory corrupted. More likely is the activation of a reset.
I recommend that teams avoid the use of the 24 volt solenoids, although that is the industry standard. Please, don't give the programming team members any more problems to deal with.
