Product Description
The AAI141-S50/A4S00 is a high-density analog input module for the Yokogawa CENTUM VP distributed control system (DCS). It provides 16 channels of 4–20 mA signal acquisition from field transmitters, using a non-isolated (common return) architecture to maximize I/O density and cabinet efficiency.
This configuration includes the A4S00 interface adapter, optimized for ATA4S pressure-clamp terminal board connectivity, enabling organized, high-density wiring. The S50 designation identifies this module as a standard analog input (non-HART), offering a cost-effective and reliable solution for monitoring applications where digital instrument diagnostics are not required.

Application
The AAI141-S50/A4S00 is ideal for large-scale monitoring projects including:
-
Water treatment facilities
-
HVAC automation systems
-
General manufacturing plants
Its 16-channel high-density layout is especially useful for collecting data from pressure, level, and flow transmitters in low-noise environments where full channel isolation is not required.
Frequently Asked Questions
Does this module support 2-wire or 4-wire transmitters?
Yes. It accepts standard 4–20 mA signals. The wiring method—2-wire (loop-powered) or 4-wire (externally powered)—is determined by the external terminal board and field power setup.
Can this module be upgraded to HART later?
No. The S50 hardware is strictly analog. For HART digital communication, the module must be replaced with an H series variant (e.g., AAI141-H50).
