The Yokogawa AAI543-S53 is a workhorse analog input/output (I/O) module designed for the FIO series. It offers both functionality and versatility for industrial automation applications.

Function: The AAI543-S53 bridges the gap between field devices and control systems. It converts analog signals from sensors (like pressure or temperature transmitters) into digital data for the control system. Conversely, it can output digital signals to actuators (like control valves).

Type: This is a 16-channel analog I/O module, meaning it can handle 16 individual analog signals simultaneously.

Features

• Universal Input: Accepts industry-standard 4-20mA or 1-5V DC signals from various transmitters.
• Dual Redundancy: Supports configuring two modules for backup in critical applications.
• HART Communication: Enables remote communication with HART-enabled devices for diagnostics and configuration. (Note: Not all AAI543 variants support HART)
• Fast Response: Handles fast-changing signals effectively (specific models only).

Technical Specifications

• Input Range: 4mA to 20mA or 1V to 5V DC
• Input Impedance: 400Ω (at 20mA) to 1000Ω (at 4mA)
• Output Type: 4-20mA DC (analog output models)
