Product Description
The AAI143-H53/K4A00 is a premium isolated analog input module within Yokogawa’s FIO series for the CENTUM VP control system. It provides 16 fully isolated 4–20 mA input channels and integrates HART digital communication for advanced device diagnostics and asset management.
The H53 specification equips the module with ISA Standard G3 conformal coating and an extended operating temperature range, ensuring reliable operation in corrosive and harsh industrial environments. An integrated transmitter power supply supports both 2-wire and 4-wire field instruments, while the /K4A00 KS cable interface (ATK4A-00) enables rapid, high-density wiring to compatible terminal boards.

Application Scenarios
The AAI143-H53/K4A00 is ideal for mission-critical control and monitoring in chemical plants, refineries, and offshore platforms.
The G3 conformal coating protects internal circuitry from sulfur- and chlorine-based corrosive gases, while full channel isolation prevents signal interference and ground-loop issues in electrically complex installations.
Technical FAQ
Q: How is the transmitter type configured per channel?
A: Each channel can be independently set for 2-wire or 4-wire transmitters using physical setting pins on the module.
Q: Which terminal board is compatible with the /K4A00 option?
A: The /K4A00 variant is designed for use with the AEA4D terminal board, connected via a dedicated KS cable for clean, high-density cabinet wiring.
