PCI321

Stepper Motor Controller with Onboard Amplifiers PCI Card

The PCI321 is a cost-sensitive stepper motor controller PCI card with amplifiers. Its rugged design features are ideal for extreme environments, ensuring a long, reliable service life.

The intelligent PCI321 board with amplifiers is an ideal solution for all applications where stepper motors must be controlled with a maximum of flexibility and a minimum of overhead. The local processor handles all high-level commands to provide maximum control for both simple and very complex applications.

The PCI321 is also available as a M-Module, VMEbus (3U and 6U) and CompactPCI (3U and 6U) product.
