Yokogawa AAI135-H50/13S00 Analog Input Module

Product Introduction

The Yokogawa AAI135-H50/13S00 is a 16-channel analog input module designed for integration within Yokogawa’s CENTUM VP and ProSafe-RS distributed control systems (DCS and SIS). Tailored for industrial environments requiring high-performance and safety-rated analog signal acquisition, this module combines high-accuracy measurement, channel isolation, and HART communication support. It is engineered for SIL2/SIL3 applications and adheres to stringent international safety standards, making it suitable for use in critical infrastructure and hazardous process environments.

Equipped with diagnostic capabilities such as open-loop detection, short circuit alerts, and input over-range protection, the AAI135-H50/13S00 ensures operational integrity. It supports 4–20 mA current input signals, commonly used across process industries, and enables reliable communication via HART protocol, providing both analog and digital data streams simultaneously.

Product Specifications

Product Applications

The AAI135-H50/13S00 is suitable for advanced safety and control systems where reliable analog signal input is critical. It is ideal for the following industries:

• Oil & Gas (Upstream & Downstream): Monitoring field instruments such as pressure and level transmitters in SIL-rated zones.

• Chemical Processing: Accurate acquisition of analog process variables in hazardous areas.

• Power Generation: Integration with turbine control systems and balance of plant (BoP) systems.

• Water and Wastewater Treatment: Data collection from pH meters, turbidity sensors, and flow transmitters.

• Pharmaceutical Manufacturing: GMP-compliant analog input handling for batch and continuous processes.

• Pulp and Paper: High-speed input for steam and chemical process control loops.

Product Advantages

• SIL2/SIL3 Compliance: Meets the most demanding safety integrity levels for safety instrumented systems (SIS).

• HART Communication Support: Reduces wiring complexity while enabling advanced diagnostics from field devices.

• High Channel Density: 16 channels per module reduce cabinet footprint and total I/O cost.

• Advanced Diagnostic Capabilities: Early detection of wiring faults, improving system reliability and troubleshooting efficiency.

• Channel Isolation: Prevents cross-talk and protects control systems from electrical faults.

• Smooth Integration: Seamlessly integrates into Yokogawa’s CENTUM VP and ProSafe-RS architecture with minimal engineering effort.

• Reliable Performance in Harsh Conditions: Wide operating temperature range and industrial-grade construction.

FAQ

1. Does the AAI135-H50/13S00 support hot-swap capability?
   No, this module does not support hot swapping. The system must be powered down before replacement.

2. Can I configure individual channels for different input types (e.g., voltage)?
   No, all channels are fixed for 4–20 mA input. Voltage input requires external signal conditioning.

3. Is HART communication enabled by default on all channels?
   Yes, HART is available on all 16 channels if the system configuration and wiring support it.

4. How is signal isolation implemented between channels?
   Each channel is galvanically isolated to prevent mutual interference and protect the system from ground loops.

5. Can the module be used in redundant I/O configurations?
   Yes, it can be used in redundant I/O systems when paired with appropriate baseplates and configuration.

6. What diagnostics does the module offer for input loop monitoring?
   The module supports open circuit, over-current, and short-circuit detection diagnostics for each channel.

7. Is the module suitable for SIL3 applications?
   Yes, when configured within a certified ProSafe-RS system, the module supports SIL3 operations.

8. How is configuration handled for this module?
   Configuration is performed using Yokogawa’s engineering tools such as SENG and PRM.

9. Can the module detect loop polarity errors?
   No, polarity reversal protection is typically handled by field instruments or wiring design.

10. Is channel calibration required?
    The module is factory-calibrated and does not require field calibration under normal operation.
