Remote I/O places input and output modules near field devices and connects them to the controller through an industrial network.
Remote I/O is relevant when selecting, integrating, replacing or troubleshooting industrial automation equipment. The exact engineering requirement depends on the controller, machine process, interfaces, safety requirements and maintenance strategy.
This definition is intended as a technical reference. Product compatibility, safety performance and final selection must be confirmed against the latest manufacturer documentation and the actual machine conditions.
