Yokogawa AIP171 Analog Input Module
Manufacturer: Yokogawa
Product Number: AIP171
Category: Analog Input Module
System Compatibility: Yokogawa AFV300/AFV400 field control systems
Number of Channels: 16
Input Signal Types: Thermocouples, RTDs, voltage, current
Resolution: 16 bits
Accuracy: ±0.1%
Product Description
The Yokogawa AIP171 is a high-precision analog input module designed for Yokogawa’s field control systems, such as the AFV300/AFV400 series. It supports multiple signal types (thermocouples, RTDs, voltage, current) and offers advanced signal conditioning for industrial process control. With 8 isolated channels and a compact design, the AIP171 ensures reliable data acquisition in harsh environments, making it ideal for applications in manufacturing, energy, and chemical processing.
Product Parameters
| Parameter | Specification |
|---|---|
| Brand | Yokogawa |
| Model | AIP171 |
| Type | Analog Input Module |
| Compatibility | AFV300/AFV400, EXAFV (explosion-proof) systems |
| Input Types | Thermocouples (K, J, T, E, R, S, B), RTD (Pt100, Pt500), Voltage (±10V), Current (4–20mA) |
| Channels | 8 (isolated) |
| Accuracy | ±0.05% (thermocouple/RTD); ±0.02% (voltage/current) |
| Sampling Rate | 100 ms/channel (max) |
| Isolation | 500V AC (channel-to-channel, channel-to-ground) |
| Power Supply | 24V DC (via system) |
| Dimensions (D×W×H) | 15.2 cm × 5.1 cm × 20.3 cm |
| Weight | 0.5 kg |
| Temperature Range | -20°C to 70°C (operating) |
Advantages and Features
- Multi-Signal Support: Handles thermocouples, RTDs, voltage, and current signals without hardware changes.
- High Accuracy: ±0.02% precision for voltage/current inputs, reducing measurement errors in critical processes.
- Isolated Channels: 500V AC isolation protects against ground loops and electrical noise.
- Compact Design: 8-channel capacity in a small form factor (15.2 cm depth) for space-constrained cabinets.
- Self-Diagnosis: Built-in error detection (open circuit, short circuit, overrange) for proactive maintenance.
Application Areas and Cases
- Industries: Oil & gas, power plants, food & beverage, pharmaceuticals.
- Case Example: A pharmaceutical plant used the AIP171 to monitor 8 temperature points (thermocouples) in a reactor system. The module’s isolation and accuracy ensured stable data collection, reducing batch rejects by 15% and improving compliance with FDA standards.
Competitor Comparison
Compared to similar analog input modules, the AIP171 offers a higher channel count (8 vs. typical 4–6) and superior isolation (500V AC vs. 250V AC). Its support for mixed signal types (thermocouple + RTD + voltage in one module) eliminates the need for multiple modules, reducing system complexity and costs.
Selection Recommendations
- Signal Type: Confirm input requirements (thermocouple/RTD/voltage/current).
- Channel Count: Match system needs (8 channels standard; expand via additional modules).
- Environment: Ensure compatibility with -20°C to 70°C operating conditions and IP54/IP65 (with enclosure) for dusty/wet environments.
- Redundancy: Pair with redundant CPU modules (e.g., CP461-50) for fault-critical systems.
Precautions
-
Installation: Use shielded cables for thermocouple/RTD signals; follow ESD protection protocols.
-
Calibration: Perform periodic calibration (every 2 years) using Yokogawa’s tools for optimal accuracy.
-
Power Stability: Ensure 24V DC supply with <10% ripple; avoid shared power buses with high-current devices.
-
Safety: Disconnect power before module replacement; verify explosion-proof certifications (EXAFV models) for hazardous areas.
-
Firmware: Update firmware regularly to access new features and bug fixes.
