Product Name: PMAC PCI 8 Axis +/-10V Controller

Product Description

The PMAC PCI 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. Its software is capable of eight axes of control. It can have up to either eight or four channels of on-board axis interface circuitry. 
The PMAC-PCI is a full-sized PCI-bus expansion card, with a small piggyback board containing the CPU board. While the PMAC-PCI is capable of PCI bus communications, with or without the optional dual-ported RAM, it does not need to be inserted into an PCI expansion slot. Communications can be done through an RS-232 or RS-422 serial port; standalone operation is possible.
