ABOUT PMAC PCI LITE

CLICK IMAGE TO ENLARGE

The PMAC PCI Lite is a member of the PMAC family of boards optimized for interface to traditional servo drives with single analog inputs representing velocity or torque commands. It is capable of eight axes of control.

The PMAC PCI Lite is a full-sized PCI-bus expansion card. The PC can communicate to PMAC through the PCI slot or through a RS-232 or RS-422 serial port if standalone operation (i.e. without a PC) is desired.
