Product Description
The AAI835-S00 is a hybrid analog I/O module for the Yokogawa CENTUM VP and FIO systems. It provides 4 isolated input channels and 4 isolated output channels in a single slot, supporting 4–20 mA current loops.
The S00 designation indicates a basic type module, optimized for high-precision signal isolation and reliable operation in non-hazardous industrial environments. It is ideal for compact control loops requiring both measurement and actuation.

Application Scenarios
The AAI835-S00 is suited for localized PID loops and small-scale process control, such as chemical dosing, pump stations, and heat exchanger control. Combining input and output channels in a single module reduces cabinet space and lowers hardware costs in distributed control systems.
Technical FAQ
Q: Does this module support HART communication?
A: No. The S00 variant is standard analog only. For HART support, use the AAI835-H series.
Q: Can inputs and outputs operate on different ground potentials?
A: Yes. Full channel isolation allows the module to handle signals from different field sources without risk of ground-loop interference.
