Foundation Fieldbus Cable is an all-digital, serial, two-way communication protocol that standardizes the interconnection of field devices at a communication rate of 34.25 kB/s. Mem Industries is the authentic suppliers of Foundation Fieldhus Cable.

The field devices are made accessible to communicate networks (running at 1 or 2.5 Mb/s), through use of linking devices. Because a simple twisted pair of wires can carry the signals between the field devices and the networks fieldbus users can reduce the amount of I/O and control equipment (due to distribution and control into the field devices). Plus, they can use fewer intrinsically safe (IS) barriers, cabinets, cables, and connectors.

With Foundation Fieldbus Cables, end users have the freedom to implement tightly integrated digital control based on a unified system architecture and a high-speed backbone, like Fieldbus High-speed Ethernet (HSE), for plant operations.

This, in turn, removes the constraints on device and sub-system interoperability.
