Product Description
The Yokogawa AAP135-S00 S2 is a high-performance pulse input interface module for the CENTUM VP Integrated Production Control System. It is designed to acquire pulse train signals from field devices such as flow meters, tachometers, encoders, and proximity switches, converting them into high-resolution digital data for monitoring, control, and totalization.
Optimized for precision frequency measurement and pulse counting, the AAP135 excels where standard analog inputs are insufficient. Advanced signal conditioning allows reliable operation with varying pulse shapes and amplitudes, even in electrically noisy industrial environments. The S2 hardware revision incorporates enhanced internal components and improved EMI resistance while maintaining full compatibility with Yokogawa FIO (Field Network I/O) architectures.

Technical FAQ
Q: What is the difference between the S1 and S2 versions?
A: The S2 revision features updated internal components and improved EMI shielding, while remaining backward compatible with existing CENTUM VP I/O nests.
Q: Does the AAP135-S00 S2 supply power to field pulse sensors?
A: No. The module processes pulse logic levels only. External power (typically 24 V DC) is required for most field sensors, depending on wiring and sensor type.
