Product Description
The AAB841-S00 S2 is a high-density analog interface module designed for Yokogawa distributed control systems. As an upgraded “S2” revision, it provides improved hardware stability and reliable signal processing for simultaneous analog input and output operations.
This module integrates 8 analog input channels and 8 analog output channels within a single slot, making it highly efficient for space-constrained control cabinets. It is designed as a non-isolated I/O module, suitable for applications where grounding conditions are well controlled or externally managed.
With fast response times—100 ms for inputs and 40 ms for outputs—the AAB841-S00 S2 enables real-time process control and accurate signal tracking. It supports both pressure clamp terminals and KS cable interfaces, ensuring flexible and secure field wiring while maintaining signal integrity in industrial environments.

FAQ
What does the S2 designation signify?
The S2 suffix indicates a second-generation hardware revision. While functionally compatible with the original AAB841-S00, it includes improved internal components for enhanced thermal stability and long-term reliability in continuous operation.
How does the non-isolated design affect installation?
Since the AAB841-S00 S2 is non-isolated, all channels share a common ground. Proper grounding of field devices is required, and external isolation may be necessary if there are significant ground potential differences between field instruments and the control system.
