Fieldbus & I/O

Fieldbus and I/O (Input/Output) refer to an industrial network system used extensively for connecting instrumentation in process automation. Operating on a multi-drop basis, fieldbus technology facilitates two-way communications among devices while reducing cable requirements in the field. The I/O system, which can be digital or analog, is integral to data transaction between operational components and the control system. With Emerson, you can find the communication solution whether you are supporting a valve system with full I/O functionality, a direct fieldbus connection without I/O, or a standalone solution. You can also choose a module with IIoT-enabled electronics and OPC-UA protocol capabilities.
