I understand, I hope correctly, that the PCI-7334 motion control board is replacing the PCI-7324. The newer (?) 7334 is much cheaper than the 7324, which is still available. My application is to control 3 stepper motors, not very fast, not very much load. Is there any reason why I should not get the 7334? That is, how does the capability compare?
The PCI-7334 is definately the way to go. The PCI-7324 is being sold primarily to people who have existing applications and are looking for the same part. Any new project should be started with a PCI-7334 and the price is set to encourage people not to go with the older hardware.
