Yokogawa AAP135-S50 Pulse Module w/ KS Adapter

Product Overview

The AAP135-S50/KSA00 (Model: AAP135) is a high-precision pulse input module designed for Yokogawa’s CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). Functioning within the FIO (Field Interface I/O) architecture, this module is specifically engineered to interface with field devices that generate pulse signals, such as positive displacement flowmeters, turbine flowmeters, and speed sensors. The AAP135-S50/KSA00 (Part Number: AAP135-S50/KSA00) supports 8 isolated channels, ensuring that high-frequency pulse counts (up to 10 kHz) are captured with absolute accuracy while protecting the system logic from field-side electrical noise.

Equipped with the /KSA00 option, this module includes a factory-installed ATK4A-00 KS Cable Interface Adapter. This configuration allows for streamlined integration with terminal boards via standard KS cables, significantly reducing wiring complexity and improving maintenance accessibility. Whether used for flow totalization or rotation speed monitoring, the AAP135-S50 (Model: AAP135) provides the deterministic data acquisition required for safety-critical and high-performance process automation.
