Details：
The Yokogawa AAI143-H00 is a heavy-duty Analog Input Module, exclusively designed for Yokogawa’s CENTUM VP and ProSafe-RS Distributed Control Systems (DCS). It is optimized for high-reliability analog signal acquisition in harsh industrial environments—such as offshore oil & gas platforms, chemical plants, or high-temperature power facilities—where resistance to extreme conditions and stable data capture are critical for process safety and control.
-----Core Specifications
The Yokogawa AAI143-H00 is categorized as an industrial-grade, enhanced-isolation analog input module, built to withstand demanding operational conditions while maintaining precision.
It features 16 independent analog input channels, each with dedicated signal processing circuits and reinforced isolation to prevent cross-channel interference—enabling simultaneous acquisition of signals from multiple field devices (e.g., pressure transmitters, temperature sensors).
For supported input signals, it covers standard industrial types:
Current signals: 4-20 mA DC (compatible with most process transmitters)
Voltage signals: 1-5 V DC
Temperature signals: Optional compatibility with thermocouple (TC, e.g., J/K/T types) and resistance temperature detector (RTD, e.g., Pt100) sensors, eliminating the need for separate temperature input modules.
Input impedance is tailored to signal types: 250 Ω for current signals (ensuring proper transmitter loading) and 2 MΩ for voltage signals (minimizing signal loss).
Isolation performance is enhanced for harsh environments:
2000 V AC isolation between input channels and the DCS backplane (tested for 1 minute)
500 V AC isolation between individual channels (tested for 1 minute)
This robust isolation suppresses electromagnetic interference (EMI) from nearby high-power equipment and protects the module from voltage surges common in industrial settings.
Power supply uses a 24 V DC industrial standard (with ±15% voltage tolerance to adapt to unstable power grids in remote locations), and maximum power consumption is 4.2 W when all 16 channels are active—suitable for high-density DCS rack configurations.
