Product Description
The AAI141-S50/K4A00 is a ruggedized 16-channel analog input module designed for the Yokogawa CENTUM VP Field Control Station (FCS). This variant is engineered for harsh industrial environments where airborne contaminants and corrosive gases may be present. The S50 designation confirms the application of a G3 conformal coating, providing enhanced protection against humidity and corrosive substances such as Hydrogen Sulfide (H₂S) and Sulfur Dioxide (SO₂).
This configuration includes the /K4A00 factory option, which integrates the ATK4A-00 KS Cable Interface Adapter. This adapter enables direct connection to AEA4D terminal boards via KS1 high-density cables, significantly reducing cabinet wiring complexity while improving signal integrity and system reliability. The AAI141-S50/K4A00 supports 16 isolated 4–20 mA current inputs, effectively decoupling field-side electrical noise from the DCS logic.

Operational Characteristics
The AAI141-S50/K4A00 is a sink-type input module, typically used in control loops where field transmitters are powered by an external 24 V DC source. Its combination of high-voltage isolation and G3 environmental protection makes it particularly suitable for offshore platforms, pulp and paper mills, and wastewater treatment facilities, where long-term reliability is critical.
Frequently Asked Questions
Q: Does the AAI141-S50/K4A00 support HART communication?
A: No. This is a standard analog input module. For HART-enabled applications, the AAI141-H50 variant should be selected.
Q: Can this module be used without KS1 cabling?
A: No. The /K4A00 version is specifically designed for KS1 cable connection to terminal boards. If direct field wiring is required, the /A4S00 (pressure clamp terminal) variant is the appropriate choice.
