Product Description
The AAI835-H50 is a hybrid analog I/O module for Yokogawa CENTUM VP and FIO systems. It provides 4 isolated input channels and 4 isolated output channels (8 channels total) for 4–20 mA signals. Integrated HART digital communication enables remote diagnostics and access to secondary variables from smart field devices. The H50 variant is suitable for standard industrial environments, offering high precision and robust isolation.
Ideal for localized PID loops, it reduces cabinet footprint by combining sensing and actuation in a single module.
