6G Controls - Leading Supplier of New & Original PLC 、DCS Parts and Automation Controller
Overview
The Yokogawa AIP571/S1 is a high-density analog input module engineered for CENTUM VP Distributed Control Systems (DCS). It acquires analog signals from field instruments such as temperature, pressure, flow, and level transmitters and converts them into precise digital data for reliable process monitoring and control. The module supports multiple input types and is built for harsh industrial environments with robust noise immunity and diagnostic capabilities.
Key Features
- High-density input: 16 isolated analog input channels in a compact module
- Universal signal compatibility: Supports 4–20 mA, 1–5 V, thermocouple, and RTD signals
- Noise-resistant: Stable operation in electrically noisy environments
- Built-in diagnostics: Wire break detection and self-test functionality
- Flexible integration: Compatible with ESB and Optical ESB bus node units
- Compact design: Space-saving for modular panel installation
