YOKOGAWA ALR121-S01 S1 Communication Module – CENTUM CS 3000 Distributed Control System
In a modern industrial plant, a single communication failure between the DCS controller and field devices can cascade into process shutdowns, production losses, and safety incidents. The YOKOGAWA ALR121-S01 S1 Communication Module is the critical link that keeps your CENTUM CS 3000 distributed control system talking to every node on the network — reliably, in real time, and without interruption. Without it, your entire automation architecture goes silent.
The ALR121-S01 S1 occupies a specialized position within the CENTUM CS 3000 series — YOKOGAWA’s globally proven DCS platform deployed across oil & gas, petrochemical, power generation, and pharmaceutical industries worldwide. As a dedicated communication interface module, the ALR121-S01 S1 ensures deterministic data exchange between the field control station (FCS) and higher-level supervisory systems, making it indispensable for plants demanding six-sigma uptime and IEC 61511 functional safety compliance.
