Product Description
The AAP149-S50 is a high-density pulse input module designed for the Yokogawa Electric Corporation CENTUM VP platform.
Unlike standard analog input modules, the AAP149-S50 is engineered to receive pulse train signals from field devices such as:
-
Turbine flowmeters
-
Tachometers
-
Power meters
-
Rotary machinery sensors
The module converts frequency-based signals into engineering values (count, frequency, or status) for precise monitoring and totalization within the Field Control Station (FCS).
With 16 isolated channels, the AAP149-S50 provides strong noise immunity and stable operation in heavy industrial environments. It supports multiple pulse signal types, making it a flexible solution for flow measurement and speed detection applications.

System Application & Integration
The AAP149-S50 is widely used in:
-
Turbine flow metering systems
-
Motor speed monitoring
-
Energy metering
-
Rotational equipment diagnostics
By handling high-speed pulse counting at the module level, it reduces CPU load on ANB10 and ANB11 node units, ensuring faster data processing and improved system efficiency.
Technical FAQ
Can this module power field sensors directly?
No. The AAP149-S50 is a passive receiving module. Active sensors requiring excitation voltage must use an external power supply.
How is signal filtering handled?
The module incorporates built-in digital filtering to suppress contact bounce and electromagnetic interference, ensuring accurate and stable pulse accumulation.
