YOKOGAWA AAB841-S00 S2 16-Channel Analog I/O Module with HART Communication and ±0.1% FS Accuracy

The YOKOGAWA AAB841-S00 S2 is a precision‑engineered analog I/O module designed for the CENTUM VP and ProSafe‑RS control systems. It integrates eight input channels (accepting 1–5 V and 4–20 mA signals) and 16 isolated 4–20 mA output channels with HART communication and ±0.1% FS accuracy. As part of Yokogawa’s high‑reliability I/O subsystem, the module ensures accurate and stable data acquisition and control in industrial automation and process control applications. Built for ruggedness, it performs reliably under harsh conditions such as high humidity, temperature fluctuations, and vibration. With support for hot‑swap and redundant configurations, the AAB841-S00 S2 is ideal for controlling actuators, drives, and control valves, making it an essential component in modern distributed control systems (DCS).
