What are common uses for remote I/O?

Because remote I/O offers significant advantages in terms of flexibility, scalability, and reduced wiring complexity, it is ideal for many applications.

Large facilities

Remote I/O is an ideal solution for large facilities that require centralized control. Remote I/O greatly reduces the amount of cabling required between field devices and PLCs that are located far from each other. Using remote I/O also allows a centralized PLC to collect input from multiple disparate stations across a facility.

Hazardous areas

Certain locations may be too hazardous for personnel to work in during operations, making maintenance and troubleshooting a real challenge. Using remote I/O, control devices like PLCs can be installed away from field instruments operating in dangerous areas. This means that workers will be able to easily access their PLCs and other components from a safe location without shutting down operations.

System upgrades

Remote I/O can be added to almost any pre-existing system, regardless of the control device manufacturer. Simply connect a communication module that supports the appropriate protocol to your controller, then connect your I/O device. This can make system upgrades easier by reducing compatibility concerns, allowing you to update your I/O without being locked into a proprietary ecosystem.
