YOKOGAWA AVR10D-Q22020
Product Name
YOKOGAWA AVR10D-Q22020 Industrial-Grade High-Precision Analog Input Module (Dedicated for Yokogawa CENTUM VP / CS 3000 Process Automation Systems)
—— A core analog signal acquisition module designed by Yokogawa for its CENTUM VP and CS 3000 distributed control systems (DCS). It specializes in collecting low-level analog signals from on-site process instruments (such as pressure transmitters, temperature sensors, and flow meters), converting them into high-precision digital signals for transmission to the DCS controller. It provides reliable data support for real-time monitoring, closed-loop control, and fault early warning of key industrial processes (e.g., petrochemical reactor temperature control, power plant steam pressure monitoring), ensuring stable and efficient operation of production systems.
2. Product Description
The YOKOGAWA AVR10D-Q22020 module takes “ultra-high acquisition accuracy + strong DCS system integration + industrial-grade anti-interference” as its core advantages, addressing three key challenges in industrial analog signal acquisition scenarios: signal distortion caused by long-distance transmission, low compatibility with DCS platforms, and poor stability in harsh electromagnetic environments. Its core values are reflected in the following aspects:
2.1 Core Functions & Technical Advantages
- High-Precision Analog Signal Acquisition
The module integrates 8 independent analog input (AI) channels, each supporting universal signal types: 4~20 mA DC (two-wire / four-wire transmitters), 0~10 V DC (voltage-type sensors), and thermocouple signals (e.g., J, K, T, E, R, S, B types) as well as RTD signals (e.g., Pt100, Cu50). For 4~20 mA DC signals, the measurement accuracy reaches ±0.02% of full scale (FS), and the sampling rate is up to 100 Hz per channel, enabling accurate capture of subtle changes in process parameters (e.g., micro-fluctuations in chemical reaction pressure). It has a built-in cold junction compensation function for thermocouple signals (compensation accuracy: ±0.1°C) and a lead resistance compensation function for RTD signals (compensation range: 0~10 Ω), eliminating measurement errors
