Yokogawa AAP135-S50/13S00 Pulse Input Module

Overview

The AAP135-S50/13S00 is an 8-channel pulse input module. It works with Yokogawa’s CENTUM CS 3000 and ProSafe-RS distributed control systems. The module accepts contact ON/OFF signals, voltage pulses, and current pulses. It suits flow measurement, pulse counting, and event detection tasks. Each channel provides electrical isolation, ensuring reliable performance and noise immunity in industrial settings.
