Description
ABB AI03
Technical Specifications:
- Channels: 8 channels (configurable for various signal types).
- Signal Support: mV, V, mA, RTD, Thermocouple.
- Resolution: 14-bit or higher.
- Update Rate: Configurable filtering and update rates.
Functional Features:
- Multi-Signal Support: Eliminates the need for separate RTD/TC modules.
- Advanced Filtering: Configurable digital filters for noisy environments.
- Linearization: Built-in linearization tables for thermocouples and RTDs.
Application Scenarios:
- High-accuracy temperature measurement.
- Laboratory and testing equipment.
- Precision process control.
Performance Parameters:
- Cold Junction Compensation: Integrated CJC for thermocouple inputs.
- Input Impedance: > 10 MΩ for voltage inputs.
Material Composition & Structural Characteristics:
- Precision Components: Low-drift resistors and high-quality ADCs.
Working Principle:
Conditioning circuits adapt to the selected signal type. For RTDs/TCs, excitation current and CJC are applied. Signals are digitized and linearized before transmission.
Installation Requirements:
- Signal Wiring: Use appropriate wire types for TCs and RTDs (e.g., extension grade wire).
- Configuration: Strictly match software configuration to physical signal type.
Usage Precautions:
- TC Polarity: Observe strict polarity for thermocouple connections.
- RTD Wiring: Configure correctly for 2, 3, or 4-wire RTD connections to avoid measurement errors.
