YOKOGAWA AIP521 S1 Control Bus Coupler Card Module For CENTUM BP DCS
Overview
The AIP521 S1 is a rugged Control Bus Coupler engineered by Yokogawa to provide high-speed, deterministic data exchange between a CENTUM VP distributed control system and field instruments. Designed for 24/7 process environments, this compact module guarantees reliable signal integrity and simplified integration across oil & gas, petrochemical, power and pharmaceutical applications.
Key Features & Benefits
• Seamless CENTUM VP Integration – Native compatibility with Yokogawa VL-NET / V-NET protocols, eliminating gateway complexity.
• Multi-Protocol Support – Additional drivers for Modbus-RTU/TCP, PROFIBUS-DP and DeviceNet allow connection of third-party sensors, actuators and drives.
• High-Speed Communication – 1 Mbps bus speed enables real-time control loops with minimal latency.
• Scalable I/O – Supports up to 256 discrete or analog points per coupler, reducing panel space and wiring costs.
• Hardened for Industry – Wide operating temperature (-20 °C to +70 °C), 5–95 % RH non-condensing, and vibration-resistant construction ensure long-term reliability in harsh plant conditions.
• Hot-Swappable & Front-Access – DIN-rail mounting and front-facing terminals simplify maintenance without shutting down adjacent modules.
