Yokogawa AAI143-S00 S1 Analog Input Module 4-20 mA 16 Channel Isolated Field Connection
Overview
The AAI143-S00 S1 is Yokogawa’s latest-generation 16-point, isolated, 4–20 mA analog input module for the CENTUM VP and CS 3000 R3 distributed control systems. Engineered for high accuracy, channel-to-channel isolation, and hot-swappable maintenance, it delivers the measurement reliability demanded by process-critical applications such as distillation, reactor control and custody-transfer metering.
Key Features
• 16 individually isolated 4–20 mA inputs (sink or source)
• 16-bit A/D resolution, ±0.1 % span accuracy, 0.02 % repeatability
• 2 ms per channel scan, 32 ms total module cycle—ideal for fast loops
• Open-circuit and over-range diagnostics reported to the system alarm list
• HART pass-through ready on every channel, enabling field-device asset management without additional hardware
• Hot-swappable from any I/O node: change modules online without process interruption
• Wide operating envelope: –20 °C … +70 °C, 5–95 % RH (non-condensing)
• SIL2-capable per IEC 61508 when used with CENTUM VP safety function blocks
