Product Description
The AAI143-H53/A4D00 is a high-density 16-channel analog input module for the Yokogawa CENTUM VP DCS. It handles 4–20 mA signals from field transmitters and features HART digital communication for advanced diagnostics. Built to ISA Standard G3 for corrosive gas resistance and an extended operating temperature range (-20 to 70 °C), this module is optimized for harsh industrial environments.
Equipped with the A4D00 interface adapter, the module is specifically designed for dual-redundant applications, connecting seamlessly to ATA4D dual-redundant terminal boards. Its non-isolated (common return) architecture provides a compact footprint while supporting high-capacity analog signal acquisition.

Frequently Asked Questions
What is the A4D00 option?
The A4D00 is a dual-redundant connector interface designed to work with ATA4D terminal boards, enabling two modules to operate in redundancy.
Does this module provide 2-wire transmitter power?
Yes, it supplies loop power (typically 19 V or higher at 20 mA) for standard 2-wire transmitters.
Can it be used in a non-redundant baseplate?
Yes, it will function in a standard baseplate, but for single-module applications, A4S00 or standard H50/H53 variants are recommended.
