Description
The
Yokogawa AAI141-H50/K4A00 is a high-performance analog input module designed for industrial automation systems, specifically engineered to monitor and transmit precise analog signals in complex control environments. As part of Yokogawa’s advanced portfolio, the
AAI141-H50/K4A00 supports 16 non-isolated input channels, accepting 4–20 mA DC current or 1–5 V DC voltage signals from 2-wire/4-wire transmitters. Its integrated HART communication (via the
-H suffix) enables digital data exchange, enhancing diagnostic capabilities and remote configuration. The module is optimized for reliability, with a compact design (0.2 kg) and compatibility with multiple connection options (pressure clamp terminals, KS cables, MIL connectors). Ideal for applications requiring real-time data acquisition and control, the
AAI141-H50/K4A00 ensures seamless integration into Yokogawa’s Centum VP DCS and other industrial control systems.

- Flexible Connectivity: Supports multiple wiring options (terminals, KS cables, MIL connectors) for easy integration into diverse industrial setups.
- Dual Redundancy Support: Compatible with dual redundant configurations, enhancing system availability in critical applications.
- Compact Design: Lightweight (0.2 kg) and space-efficient, suitable for dense control panels.
Industries: Manufacturing, energy, chemical processing, water treatment, and oil & gas.
Scenarios: Monitoring pressure/temperature transmitters, flow meters, and process sensors in DCS systems.
Case Study: A chemical plant in Southeast Asia deployed the AAI141-H50/K4A00 to monitor 16 temperature sensors in a reactor. The module’s HART functionality enabled real-time troubleshooting of sensor anomalies, reducing unplanned downtime by 20% and improving process efficiency.
Compared to similar analog input modules, the AAI141-H50/K4A00 stands out with:
- Higher Channel Density: 16 channels (vs. 8–12 channels in 竞品).
- Integrated HART Support: Built-in digital communication (eliminating need for external adapters).
- Wide Voltage Range: Transmitter power supply (14.8–26.4 V DC) accommodates diverse field devices.
- Lower Drift: Industry-leading temperature stability (±16 μA/10°C vs. ±20–25 μA/10°C in comparable models).
AAI141-H50/K4A00
- Compatibility: Ensure compatibility with your DCS (e.g., Yokogawa Centum VP) and HART-enabled devices.
- Environment: Verify temperature range (-20°C to 70°C with G3 option) and explosion protection requirements (non-isolated design; use barriers for hazardous zones).
- Connection: Choose between terminal blocks (ATA4S-00), KS cables (ATK4A-00), or MIL connectors (ACCC01) based on cabling standards.
- Budget: Balance channel density and HART features against cost (competitive pricing vs. single-function modules).
-
Wiring: Separate analog/digital cables and use shielded wires to minimize noise. Ground shielding layers properly.
-
Power Supply: Ensure transmitter voltage (14.8 V min. at 20 mA) meets field device requirements; account for wiring voltage drop.
-
HART Configuration: Update EB401 firmware (rev. 2+) for remote node HART functionality.
-
Maintenance: Regularly inspect connectors for corrosion; replace faulty modules immediately to avoid system-wide failures.
