Product Overview
The AAV141-S50 analog input module from Yokogawa is engineered for high-density voltage signal acquisition within CENTUM distributed control systems. It provides 16 non-isolated input channels designed specifically for 1–5 V DC process signals. With its compact form factor and low power demand, this module is well suited for control cabinets where space efficiency and stable analog performance are required.
Designed as a standard, non-explosion-proof variant, the AAV141-S50 is typically deployed in general industrial environments where intrinsic safety is not mandated.
System Compatibility
The AAV141-S50 is natively integrated into Yokogawa CENTUM DCS architectures and is commonly used in I/O nodes for continuous process monitoring. It supports deterministic data acquisition and consistent signal resolution when paired with Yokogawa control stations.

Related Models Comparison
Compared with isolated analog input variants in the AAV series, the AAV141-S50 offers a more compact and cost-efficient solution where channel-to-channel isolation is not required. For applications involving higher noise immunity or mixed signal grounds, isolated AAV models may be more appropriate.
FAQ
Q: Can the AAV141-S50 accept current signals such as 4–20 mA?
A: No. This module is designed exclusively for voltage inputs in the 1–5 V DC range.
Q: Is this module suitable for hazardous areas?
A: No. The S50 configuration does not include explosion protection and should only be used in non-hazardous locations.
Q: Does the module provide channel isolation?
A: No. All channels share a common reference and are non-isolated.
