The PACSystems™ RX3i CPE302 is a high-performance CPU designed for real-time control of machines, industrial processes, and material handling systems. The CPU communicates with programming tools via an integrated Ethernet port or RS-232 serial port, and interfaces with I/O and Intelligent Option modules through a dual PCI/Serial backplane.
