Yokogawa AAR145-S50
Product Introduction: A high-performance analog input module designed for Yokogawa’s CENTUM series DCS. It provides 16 isolated channels for accurate measurement of resistance temperature detectors (RTDs) and potentiometer (POT) position signals, offering reliable data acquisition for temperature and position monitoring in industrial processes.
Technical Specifications:
- Input Type: 16 isolated channels, supporting RTD (Pt100, etc.) and potentiometer (POT) inputs.
- Potentiometer Input: Resistance range: 100 Ω to 10 kΩ; span resistance ≥ 50% of total resistance.
- RTD Input: Supports standard 3-wire RTD configurations; accuracy: ±150 mΩ.
Detailed content
- Isolation: Channel-to-channel isolation (200 V AC for 1 min); channel-to-system isolation (500 V AC for 1 min, 1500 V AC per card).
- Data Update Cycle: 1 second for all channels.
- Power Consumption: Max. 350 mA at 5 V DC.
- Weight: Approx. 0.3 kg.
- Operating Temperature: -20°C to +70°C (G3 harsh environment option).
Key Features:
- High channel density (16 channels) with full galvanic isolation for noise immunity and safety.
- High measurement accuracy for both RTD temperature and potentiometer position signals.
- Low temperature drift ensures stable performance over a wide operating temperature range.
- Designed for harsh industrial environments (G3 option) with resistance to corrosive gases.
- Easy integration with CENTUM DCS for seamless data integration into control strategies.
- Diagnostic capabilities for fault detection and system health monitoring.
Applications:
- Temperature monitoring using RTD sensors in chemical, petrochemical, and power plants.
- Position and displacement measurement using potentiometers in valve actuators and dampers.
- Process control loops requiring precise temperature or position feedback.
- Safety monitoring systems for critical equipment temperatures.
- Industrial furnace and boiler temperature profiling.
