Product Description

The AAI543-H00 S1 is a high-density, isolated analog output module designed for the Yokogawa CENTUM VP control system. It provides 16 channels of 4–20 mA current output, enabling precise control of final control elements such as modulating valves, actuators, and motor starters.

Equipped with a built-in HART modem, the module allows bi-directional digital communication, enabling remote device monitoring and configuration without interrupting the analog process signal.

Key Features

• Intelligent Diagnostics: Open-circuit detection (<0.65 mA) for immediate alerts on field wiring failures

• High-Speed Response: 10 ms data update cycle for fast process loops

• Enhanced Safety: 1500 V AC galvanic isolation between outputs and system backplane

• Redundancy Compatible: Supports dual-redundant configurations to maintain output continuity during failures

Technical Specifications

Industrial Applications

The AAI543-H00 S1 is widely used in oil and gas refining, power generation, and pharmaceutical manufacturing. It is especially suited for controlling smart valves and actuators that require HART-based diagnostics, calibration, and status monitoring, helping maintain high plant availability and safety.

Technical FAQ

Q: What is the advantage of the 750 Ω load resistance?
A: The high load resistance allows the module to drive signals over long distances or through intrinsic safety barriers without signal degradation or loop failure.

Q: Does the AAI543-H00 support hot-swapping?
A: Yes. When installed in a redundant CENTUM VP configuration, the module can be replaced while the system is live, without interrupting field output signals.
