Product Description
The AAI841-S00 S2 is a high-density hybrid analog module for the Yokogawa CENTUM VP distributed control system. This versatile unit provides 8 channels of 4–20 mA input and 8 channels of 4–20 mA output, managing up to 8 complete control loops in a single slot.
As a non-isolated "Standard Type" module, it offers compact, cost-effective performance for applications where field devices share a common ground. The S2 revision ensures modern hardware compatibility and long-term reliability in existing DCS installations.
Key Features

Water treatment systems
It is perfect for applications where 4–20 mA signaling is standard and full galvanic isolation is not required.
Technical FAQ
Q: Can the AAI841-S00 S2 support HART communication?
A: No. The standard S-series (AAI841-S00) does not support HART. For smart transmitters requiring digital diagnostics, the AAI841-Hxx variant should be used.
Q: What is the benefit of the non-isolated design?
A: Non-isolated architecture allows a compact, cost-effective module. Ideal for systems where all field instruments share the same power source or where ground potential differences are negligible.
