Stepper Motor Controller with Onboard Amplifiers

The CPCI321 is a cost-sensitive stepper motor controller CPCI board with amplifiers. Its rugged design features are ideal for extreme environments, ensuring a long, reliable service life.

The CPCI321 is an ideal solution for all applications where stepper motors must be controlled with a maximum of flexibility and a minimum of overhead.

The CPCI321 is also available in 6U form factor and as a M-Module, PCI and VMEbus (3U and 6U) product.
