Festo’s CPX-AP-I Remote I/O enables faster scan rates and higher performance of mixed valve terminals and I/O systems.

Festo announced the CPX-AP-I, an IP65/IP67-rated remote I/O system compatible with most communication protocols, including EtherNet/IP, PROFINET and EtherCAT. Directly mountable on machines, the CPX-AP-I allows valve terminals to be moved closer to pneumatic cylinders. It handles up to 80 I/O modules, in a mix of digital I/O, analog I/O, I/O-Link, and valve terminals, at distances between modules up to 49 feet (15 meters). Process data in and out of each bus module is as much as two kilobytes. Scan cycles for a mix of both valve terminals and I/O are below one millisecond. Communication and voltage supply are via two separate connecting cables that are also galvanically isolated, eliminating the potential for stray currents. Two separate wires enable the creation of voltage zones that provide reliable control for a host of machine processes.
