The Emerson KJ2004X1-BA1 VS3201 is a Remote Interface Unit (RIU) used in DeltaV distributed control systems (DCS) to provide secure and reliable communication between control system cores and remote I/O subsystems.
This module is designed for system expansion, remote rack integration, and distributed architecture deployment, allowing engineers to place I/O closer to the field while maintaining centralized control logic. It is widely applied in oil & gas, petrochemical, offshore platforms, and power generation facilities, where distance, redundancy, and signal integrity are critical design factors.
The VS3201 designation typically represents a configuration/variant identifier within Emerson DeltaV RIU architecture, ensuring compatibility with specific system versions and redundancy schemes.
