Emerson DeltaV™ S series 4-port FF fieldbus I/O

Emerson DeltaV™ S series 4-port FF fieldbus I/O

Product Description

FF fieldbus I/O is a modular subsystem that enables digital communication with field devices, enhancing your input/output capabilities and facilitating your access to more information about the process (rather than traditional I/O subsystems). This fieldbus I/O greatly improves the device diagnosis that affects your control strategy and can send device failure alerts to operators. If you wish to obtain a safe, efficient, economical and distributed process control system, use DeltaV™ FF fieldbus I/O.
