XC and EX Axioline F I/O

Phoenix Contact's EX I/O is designed for installation in Class I, Div 2 environments and allows safe connection to sensors and actuators located in hazardous Zone 1 and 0 environments. These environments require extra precautions because they may contain flammable substances such as gases, dusts, and fibers. The modules limit available current to the connected sensors, reducing the possibility of combustion. The design provides the connection of non-safe 24 V power on the top side of the module and current-limited safe signals at the blue I/O connectors. This unique layout provides the required separation between safe and non-safe signals. With this design, Axioline allows XC and traditional I/O modules to be combined in a single I/O station.

XC I/O modules are tested for more stringent approvals, such as UL-Ex approvals for Zone 2 installation, IECEx, and ATEX. This selection of Axioline controllers, bus interfaces (BKs), and I/O modules are conformally coated and can be used in traditional applications requiring only Class I, Div 2 I/O, or they can be combined with the EX for hybrid applications.
