YOKOGAWA NFLR121-S00 Serial Communication Module – STARDOM FCN/FCJ Series
When a serial communication link fails in a distributed control system, the consequences cascade instantly — field devices go silent, SCADA loses visibility, and operators are left flying blind in a process that cannot afford downtime. In oil & gas, water treatment, power generation, and chemical processing, even a brief loss of serial communication can trigger emergency shutdowns, product loss, or safety incidents. The YOKOGAWA NFLR121-S00 is the purpose-built solution that keeps these critical data highways alive.
The NFLR121-S00 is a dedicated Serial Communication Module designed for YOKOGAWA’s STARDOM FCN/FCJ autonomous controller platform — one of the most widely deployed distributed control architectures in global process industries. Within the STARDOM ecosystem, the NFLR121-S00 occupies a critical role: it bridges legacy serial field devices (RS-232C and RS-485 protocols) with the modern Ethernet-based control network, enabling seamless integration of instruments, drives, and third-party controllers that predate industrial Ethernet. Its proven reliability and YOKOGAWA’s global installed base make it a first-choice component for both greenfield projects and brownfield upgrades worldwide.
