Product Description
The AAI841-H50 is a hybrid analog I/O module for Yokogawa CENTUM VP and ProSafe-RS systems. It provides 16 channels (8 input / 8 output) for 4–20 mA signals, integrating HART digital communication for real-time device diagnostics and remote parameter adjustment. The H50 suffix indicates a HART-enabled standard-temperature module for non-hazardous locations.
This module is ideal for localized control loops with equal numbers of sensors and actuators, offering high-speed control while reducing cabinet footprint.

Application Scenarios
The AAI841-H50 is ideal for small to medium PID loops such as pressure regulation stations, chemical injection skids, or other localized control tasks where both sensing and actuation are required in a single module. Its integrated HART capability allows monitoring of secondary variables and device health from smart field transmitters.
Technical FAQ
Q: Can this module interface with smart HART transmitters?
A: Yes. The AAI841-H50 is HART-enabled, allowing the control system to capture secondary variables and device diagnostics.
Q: Does it supply power to 2-wire transmitters?
A: The module conditions signals only. Transmitter power is provided via the associated terminal block or field wiring assembly, depending on system configuration.
