Product Introduction
A drifted thermocouple input can mask a real temperature deviation before the alarm ever trips. The YOKOGAWA AAT141-S00 S2 is a 16-channel isolated thermocouple and millivolt input module for CENTUM CS 3000 DCS, used to convert low-level temperature signals from thermocouples and mV-output sensors into reliable digital process values.
The “-S00” suffix identifies this as a standard-type, basic-option AAT141 module; “S2” is the style revision. The AAT141 family supports 16 isolated channels and is commonly used for furnace, reactor, heat-exchanger, and pipeline temperature loops. Because the exact terminal interface option is not specified here, please confirm whether your existing card uses ATT4S, ATT4D, ACCC01, or another terminal/cable option before placing the order.

Key Selling Points & Differentiators
- 16-channel isolated TC/mV input for CENTUM CS 3000 temperature loops.
- Suitable for thermocouples and low-level mV sensors where isolation matters.
- Standard-type, basic-option module with S2 style revision.
- Factory-sealed surplus inventory with visual QA and 12-month warranty.
- Not recommended for RTD-only applications; consider AAR181 or AAR145 for PT100 inputs.
Quality Transparency SOP
- Visual inspection: Verify label, “AAT141-S00,” “S2” style revision, connector pins, and housing for moisture, corrosion, or handling damage.
- Seal verification: Confirm original anti-static bag, desiccant, and factory labeling before opening.
- Backplane power check: Verify 5 VDC and 24 VDC rails before insertion to avoid unstable channel readings.
- Channel accuracy test: Use a precision mV/TC simulator to verify multiple channels against known thermocouple or mV setpoints.
- Isolation test: Perform insulation resistance checks between input channels and system ground per Yokogawa specifications.
- Terminal interface check: Confirm the correct terminal board or cable option matches the existing wiring before installation.
Technical Risk Avoidance
❗ Confirm the terminal interface option. AAT141 may be supplied with ATT4S, ATT4D, ACCC01, or other options; mismatched interfaces can prevent proper wiring.
❗ Verify the thermocouple type in the DCS configuration. Incorrect TC type selection will cause large temperature reading errors even if the module is healthy.
❗ Do not use this module for RTD/PT100 inputs unless explicitly confirmed. RTD applications should use AAR-series modules.
❗ In redundant or mixed-node configurations, ensure the replacement module matches the original suffix and style revision.
Buyer’s FAQ
Is the YOKOGAWA AAT141-S00 S2 a genuine OEM part?
Yes. It is an original Yokogawa AAT141 series thermocouple/mV input module supplied as new surplus, factory sealed when available. We do not rebrand or relabel third-party substitutes.
What does “S00 S2” mean?
“-S00” means standard type with the basic option. “S2” is the style revision. If your original card has a different suffix such as -S03, -S50, or -S53, the environmental or redundancy options may differ.
Is this module isolated?
Yes. The AAT141 family is specified as a 16-channel isolated thermocouple/mV input module.
Can I replace an AAT141-S03 or AAT141-S50 with this module?
Functionally it is the same AAT141 TC/mV input family, but the suffix differences may affect environmental rating, redundancy, or terminal options. Confirm your engineering data before substitution.
What warranty do you offer?
A 12-month warranty against manufacturing defects and DOA issues. Damage from incorrect wiring, wrong TC type configuration, overvoltage, or mismatched terminal interface is not covered.
