The CX8091 includes the smallest Embedded PCs available from the company. With support of the OPC UA protocol, a 400 MHz ARM9 CPU and a wide range of connectable K-bus or E-bus I/O terminals, it represents a universal small controller for almost any application. In addition, the CX8091 is fully interoperable with power measuring terminals to serve as a compact data collector that supplies all information to enable comprehensive energy management. The Embedded PC is a flexible and compact controller with a switched Ethernet port and supports OPC UA. Bus Terminals (K-bus) and EtherCAT terminals (E-bus), as modular I/O systems, can be connected directly to, and automatically identified by the Embedded PC. In this way, a multitude of signals can be acquired locally – for example, via the numerous I/O terminals for energy data acquisition and many other types of measurement.
