The Yokogawa AAP135-S00/K4A00 delivers precision pulse input processing for Centum VP and CS 3000 distributed control systems. It accurately measures rotational speed, flow rates, and accumulated totals from field instruments. This module provides reliable data acquisition for critical rotating equipment in demanding process applications.
Advanced Pulse Counting with Enhanced Termination
We engineer this module with 8 isolated pulse input channels for comprehensive monitoring of multiple rotating devices. The /K4A00 suffix indicates KL5 connector termination for secure and reliable field wiring connections. Each channel accepts signals from turbine flowmeters, encoders, and magnetic pickups with high accuracy. Consequently, process engineers obtain superior measurement performance with robust field termination.
Technical Specifications and Physical Characteristics
The AAP135-S00/K4A00 utilizes high-speed counting circuits for precise frequency measurement up to 10 kHz. It features channel-to-channel isolation to prevent interference between different input signals. The module provides both instantaneous frequency and 32-bit accumulated total values per channel. The KL5 connector interface ensures reliable connections in high-vibration industrial environments.
