EMERSON FP20-6TX2TX Network Switch Module – DeltaV FP20 Fieldbus Power Series
When a network switch module fails inside a DeltaV distributed control system, the consequences extend far beyond a single device going offline. Field devices lose communication, process data stops flowing to the controller, and operators are left managing a critical industrial process without real-time visibility. In high-stakes environments such as oil & gas refineries, chemical plants, and power generation facilities, even minutes of unplanned downtime can translate into significant production losses and safety risks. The EMERSON FP20-6TX2TX — also identified by part numbers KJ1611X1-BA1 and 12P4448X032 — is the purpose-built network switch module designed to prevent exactly this scenario.
Within the DeltaV FP20 Fieldbus Power series, the FP20-6TX2TX occupies a critical integration role. It provides six 10/100BASE-TX RJ45 ports and two additional TX uplink ports, enabling seamless Ethernet connectivity between field junction boxes and the DeltaV controller network. As a genuine Emerson part, it is engineered to meet the rigorous demands of continuous industrial operation, making it one of the most trusted network infrastructure components in global process automation installations.
