Description
Key Features
Signal Input
- Type: 16 channels of 4-20mA DC current input (non-isolated)
- Resolution: 16-bit analog-to-digital conversion
- Accuracy: ±0.1% of full scale (typical)
- Sampling Rate: Configurable per channel (e.g., 10–100 ms update time)
Compatibility & Integration
- System Compatibility:
- Works with FIO (Field I/O) units (e.g., AFV30D, A2FV50S)
- Integrates with CENTUM VP DCS and Engineering Windows (EWS)
- Hot-Swappable: Supports online replacement in redundant configurations
- Wiring:
- Terminal block connections for field devices
- Supports HART communication (if enabled in firmware)
Diagnostics & Protection
- Fault Detection: Open wire, over-range, under-range, and signal drift alarms
- LED Indicators: Per-channel status (active, fault, communication)
- Noise Immunity: Shielded terminal design for EMI/RFI protection
Environmental & Mechanical
- Operating Temperature: -20°C to +70°C
- Isolation: Non-isolated (all channels share a common ground)
- Certifications: Complies with IEC 61131-2 for industrial use
Suffix Code Breakdown (AAI141-S2)
| Suffix | Description |
|---|---|
| -S2 | Hardware revision (Style 2) |
| -E | Explosion-proof variant (e.g., AAI141-S2-E) |
Note:
- For isolated 4-20mA inputs, use the AAI143 series.
- Non-isolated design requires careful grounding to avoid noise interference.
Typical Applications
- Process Monitoring: Pressure, flow, level, and temperature transmitters
- Batch Control: High-density analog signal acquisition
- Safety Systems: Integration with ProSafe-RS for critical measurements
Installation & Configuration
- Slot Assignment: Install in FIO I/O unit slots (refer to FCU manual).
- Wiring:
- Use shielded twisted-pair cables for noise reduction.
- Ensure proper grounding to avoid ground loops.
- Configuration:
- Set input ranges and alarms via CENTUM VP Engineering Studio.
- Calibrate using Yokogawa’s Field Device Manager (FDM).
