AAP135-S00 | Yokogawa CENTUM VP/FIO Pulse Input Module

Product Overview

The Yokogawa AAP135-S00 functions as a high-precision Pulse Input Module for the CENTUM VP and CS 3000 FIO (Field network I/O) architectures. This module captures frequency and pulse signals from field devices such as flowmeters, tachometers, and displacement sensors. It converts these rapid pulses into accurate digital data for the Distributed Control System (DCS) to calculate flow totals, rotational speeds, or position data. Although the manufacturer has officially discontinued this series, we maintain 100% brand new, original factory stock to support the maintenance and expansion of your existing control infrastructure.

Engineering Advantages

The AAP135-S00 optimizes signal acquisition for high-speed dynamic processes through specialized hardware engineering:

• High-Speed Pulse Tracking: This module accurately captures high-frequency inputs that standard digital input cards might miss. This ensures precise totalization for turbine flowmeters and exact RPM monitoring for rotating machinery.

• Total Channel Isolation: The hardware provides complete electrical isolation between every channel. This architecture eliminates ground loops and prevents field-side electrical noise from corrupting the signal integrity of adjacent channels or damaging the system backplane.

• Robust Signal Filtering: Integrated hardware filters remove signal "bounce" and electromagnetic interference (EMI). This ensures the DCS receives a clean pulse count even when field wiring runs parallel to high-voltage power cables or near variable frequency drives (VFDs).

• Seamless Legacy Integration: As a discontinued component, this brand new unit allows you to replace failed modules or add new points to existing CENTUM systems without upgrading your entire I/O nest. The "plug-and-play" design facilitates rapid installation onto standard FIO baseplates.

FAQs

• Can the AAP135-S00 handle both 2-wire and 3-wire pulse sensors? Yes. The module supports various input configurations, including dry contacts and active voltage pulses, making it compatible with a wide range of industrial flow and speed transmitters.

• How does this module communicate with the CENTUM VP controller? The module slides into an FIO baseplate (nests) and communicates via the high-speed F-bus backplane, allowing the controller to access pulse counts and frequency data in real-time.

• Is this a refurbished or used unit? No. We guarantee that every AAP135-S00 we ship is 100% brand new and original. Each unit arrives in its original manufacturer packaging with the factory seal intact, backed by our 1-year warranty.

• Does this module support redundancy? You can configure the AAP135-S00 in a dual-redundant setup when installed in compatible redundant slots on the FIO baseplate, ensuring continuous pulse counting even if a single module hardware fault occurs.
