FOXBORO H929049B0500
Product Name
FOXBORO H929049B0500 High-Precision Analog Input (AI) Module (Distributed Control System Dedicated)
—— A core I/O component of Foxboro’s I/A Series DCS, designed for accurate acquisition of analog process signals (e.g., temperature, pressure, flow) in industrial process control. It is widely applied in petrochemicals, oil & gas, power generation, and chemical processing, serving as a critical interface between field sensors and the DCS to ensure real-time, reliable process monitoring.
2. Product Description
The FOXBORO H929049B0500 module excels in “high measurement accuracy + industrial-grade robustness + seamless DCS integration,” addressing three core pain points in process control: signal distortion from harsh environments, low compatibility with legacy DCS, and insufficient diagnostic capabilities. Its key values are as follows:
2.1 Core Functions & Technical Advantages
- High-Precision Signal Acquisition: Features 8 independent analog input channels, supporting universal signal types: 4~20mA DC (current), 0~5V DC/0~10V DC (voltage), and RTDs (Pt100, Pt1000) for temperature measurement. Delivers a measurement accuracy of ±0.05% of full scale (FS) for current/voltage signals and ±0.1% FS for RTD signals, ensuring precise capture of subtle process changes (e.g., small pressure fluctuations in chemical reactors).
- Noise Suppression & Signal Integrity: Integrates 24-bit delta-sigma ADCs (Analog-to-Digital Converters) with a sampling rate of 10 Hz per channel, minimizing quantization
