Axioline family remote I/O system for the control cabinet and field installation

Remote I/O systems for the control cabinet and field installation

Choose from an extensive range of remote I/O systems for the control cabinet, also for particularly fast data communication. Implement safety applications with our PROFIsafe modules, for example, or with no safety controller at all by using SafetyBridge Technology. Our I/O systems can be combined perfectly with all Phoenix Contact programmable logic controllers.

For decentral automation without a control cabinet, you can use I/O modules in a block design with high functionality and a particularly robust design for harsh industrial environments. You can extend the scope of functions of your application by using digital I/Os along with an IO-Link master and the corresponding IO-Link devices.
