Original Yokogawa 16-Channel Analog Module | AAT141-S00 S2

Product Details

Product Overview

The Yokogawa AAT141-S00 S2 serves as a high-density, 16-channel isolated analog input module specifically engineered for CENTUM VP and CENTUM CS distributed control systems. This module provides high-precision acquisition of Thermocouple (TC) and Millivolt (mV) signals, converting low-level sensor voltages into digital data for critical process monitoring. By incorporating electrical isolation for every channel, the AAT141-S00 S2 eliminates common-mode noise and ground loop interference, ensuring measurement stability in volatile industrial environments such as power plants and chemical refineries.

Part Number Breakdown: AAT141

• AAT141: Basic Model Code for Thermocouple/mV Input Module (16-channel, Isolated).

• -S: Standard Type.

• 0: Always 0.

• 0: Basic Software.

• S2: Style Code (Indicates the latest hardware revision for improved signal stability and reliability).

Technical Specifications

Engineering Advantages

• Interference-Free Acquisition: Each of the 16 channels features independent electrical isolation. This hardware architecture prevents a single faulty thermocouple or electrical surge from affecting the data integrity of the other 15 channels.

• Broad Millivolt Support: The module handles a wide voltage range from –200 mV to +200 mV, allowing it to interface with a variety of specialized sensors beyond standard thermocouples, such as heat flux sensors or oxygen probes.

• High-Density Thermal Mapping: The compact 3.4 cm width allows engineers to pack 16 channels into a single slot. This density reduces the total number of I/O nodes required for large-scale boiler or reactor temperature monitoring.

• Optimized for Harsh Environments: The S2 style revision incorporates ruggedized internal components that maintain calibration accuracy even when subjected to the thermal cycling and vibration typical of industrial control cabinets.

• Seamless DCS Integration: The AAT141-S00 S2 communicates natively with Yokogawa Field Control Stations (FCS). This allows for rapid software configuration and automatic cold-junction compensation via the CENTUM engineering station.

FAQs

Q1: Does the AAT141-S00 S2 support cold-junction compensation (CJC)?

A1: Yes. When paired with the appropriate pressure-clamp terminal block or spring-clamp terminal block, the module performs automatic cold-junction compensation to ensure accurate thermocouple temperature readings.

Q2: Can I mix different thermocouple types on the same module?

A2: Yes. You can configure each channel individually within the CENTUM software. The AAT141-S00 S2 accommodates various standard thermocouple types (e.g., K, J, T, E, R, S, B, N) simultaneously across its 16 points.

Q3: Is this an original Yokogawa part?

A3: We supply only 100% Brand New and Original Yokogawa modules in their original factory packaging. Each unit includes a 12-month industrial warranty for quality assurance.

Q4: What is the difference between Style S1 and Style S2?

A4: Style S2 represents the most recent hardware version. It maintains full backward compatibility with Style S1 but features refined internal circuitry designed to enhance long-term reliability and resist environmental degradation.
