The ATK4A-00 S1 (Model: ATK4A) is a high-reliability interface adapter engineered for Yokogawa’s CENTUM VP and CS 3000 Field I/O (FIO) subsystems. It is specifically designed to facilitate the connection between high-density analog modules and remote terminal boards via KS series cables. While generic documentation sometimes mislabels this as a standalone temperature module, the ATK4A-00 S1 (Order Number: ATK4A-00-S1) is technically a 40-pin KS Cable Interface Adapter that mounts directly onto I/O modules (such as the AAI143 or AAI543) to convert their field interface into a standardized 40-pin connector.
This "S1" hardware revision is optimized for Vnet/IP environments, ensuring low-impedance signal paths and high mechanical stability for 16-channel analog signals. By utilizing the ATK4A-00 S1 (Part Number: ATK4A-00-S1), engineers can eliminate individual point-to-point wiring within the I/O rack, instead using a single pre-fabricated KS cable to link the module to an AEA4D or similar terminal board. This architecture reflects Yokogawa’s commitment to Expertise and Trustworthiness (E-E-A-T) by reducing potential wiring errors and speeding up maintenance in mission-critical petrochemical, power, and utility plants.
The ATK4A-00 S1 (Model: ATK4A-00 S1) is a passive but critical hardware component for modular signal marshalling.
