Product Description

The AAI143-H00 S1 is an advanced 16-channel analog input module designed for the Yokogawa CENTUM VP Distributed Control System. This H-type module is optimized for smart field instrumentation and integrates HART (Highway Addressable Remote Transducer) communication, enabling simultaneous analog measurement and digital diagnostics.

By combining fully isolated 4–20 mA input processing, built-in transmitter power, and high-speed data updates, the AAI143-H00 S1 supports precise process monitoring and advanced asset management in mission-critical industrial environments.

Key Features

• HART Communication: Simultaneous transmission of 4–20 mA analog signals and digital diagnostic data

• High-Speed Performance: 10 ms data update period for near real-time process response

• Integrated Transmitter Power: Per-channel loop power (≥19.0 V at 20 mA) with 25 mA current limiting

• Flexible Transmitter Support: Configurable per channel for 2-wire or 4-wire transmitters

• Full Channel Isolation: Prevents ground loops and cross-channel interference

Technical Specifications

Industrial Applications

The AAI143-H00 S1 is widely used in industries relying on smart transmitters and advanced diagnostics, including:

• Advanced chemical processing

• Pharmaceutical manufacturing

• Power generation and turbine control

It is ideal for applications requiring remote calibration, device health monitoring, and fast loop response, without additional field wiring.

Technical FAQ

Q: Can the AAI143-H00 S1 directly power 2-wire transmitters?
A: Yes. Each channel includes an internal power supply providing a minimum of 19.0 V at 20 mA, allowing direct connection of 2-wire transmitters.

Q: What is the benefit of the 10 ms update period?
A: The fast update rate enables near-instant detection of process changes, which is critical for high-speed applications such as turbine control, compressor surge protection, and rapid interlock response.
