Product Overview
The Yokogawa AAI841-S00 is an 8-channel analog input and output module for CENTUM distributed control systems.
Engineers use this non-isolated module to control up to 8 process loops with high signal speed.
It supports dual-redundant configurations to ensure continuous system operation in critical applications.
Integrated HART communication allows direct transmission of smart field device diagnostics.

Installation Guide & Compatibility
- Mount the module securely into the designated CENTUM DCS node slot.
- Configure each channel for 2-wire or 4-wire transmitters using onboard setting pins.
- Connect external wiring using pressure clamp terminals or pre-assembled KS/MIL cables.
- Verify full physical fit with standard Yokogawa system rack enclosures.
Diagnostics, Maintenance & Applications
The AAI841-S00 triggers open-circuit detection when output current drops below 0.65 mA.
Engineers easily replace modules during scheduled maintenance due to simple wiring connections.
Ideal for oil refineries, chemical processing plants, and power generation facility control loops.
