Description
The Yokogawa AAB841-S00 is a high-accuracy analog I/O module engineered for advanced industrial automation systems. It features eight analog input channels and eight analog output channels, allowing flexible signal handling across a wide range of control applications.
Each input channel supports 1–5 V DC voltage signals, while the output section provides 4–20 mA DC current signals for precise field device control. Moreover, its compact design and low power consumption make it ideal for distributed control systems that require dependable analog signal processing.
Functional Highlights
- Dual Functionality: Combines both analog input and output channels in a single module for simplified wiring and reduced footprint.
- High Accuracy: ±4 mV for voltage inputs and ±48 µA for current outputs ensure stable signal integrity.
- Fast Response: Input step response of 100 ms and output response of 40 ms deliver real-time performance.
- Low Temperature Drift: Maintains accuracy within ±0.1% per 10°C, even under varying plant conditions.
- Flexible Connection Options: Supports pressure clamp terminals or KS cables for quick installation.
In addition, the module’s non-isolated architecture improves operational efficiency and reduces cost in compact system designs.
