Product Precautions
- AAT141-S00 S2 receives thermocouple and low-level millivolt signals for process-temperature measurement.
Measurement role: 16 isolated TC/mV inputs
Sensor flexibility: Channel-specific input selection
Service focus: Preserve cold-junction and channel settings

AAT141-S00 S2 is a 16-channel isolated temperature-input module in the Yokogawa FIO family. Each channel can be configured for a supported thermocouple type or a millivolt signal, allowing the same module to acquire several measurement types in an engineered station.
The referenced thermocouple set includes J, K, E, B, R, S, T and N. Two millivolt ranges, −100 to +150 mV and −20 to +80 mV, are documented. The base design updates input data each second, so temperature-control logic and alarming should use the appropriate scan and filtering configuration.
Thermocouple measurement depends on correct sensor type, polarity, cold-junction arrangement and the installed terminal. Yokogawa cautions against grounded thermocouples where multiple ground paths would affect measurement. Preserve the exact module marking and configured channel types during replacement.

Technical notes
Technical basis: Yokogawa GS 33K50F60-50E, Temperature Input Modules for FIO.
Applicability: AAT141-S reference data describes the base module. The S2 style, when present, is retained as the offered marking without an assumed electrical difference.
Integration focus: Thermocouple type, polarity, compensation and alarm configuration must follow the installed measurement channels.
FAQ View All FAQ
-
Why can a temperature reading drift after AAT141-S00 S2 is changed?Check cold-junction compensation, sensor type, terminal seating and channel configuration before judging the module.
-
How can a thermocouple-type mismatch be recognized after replacing AAT141-S00 S2?Compare the configured type with the fitted sensor and a known reference temperature; a mismatch can produce a systematic reading error even when wiring is intact.
-
What should be checked when a reading on AAT141-S00 S2 has reversed polarity?Inspect the thermocouple polarity and terminal wiring against the original channel schedule.
-
Why should grounded thermocouples be reviewed for AAT141-S00 S2?Multiple ground paths can disturb low-level thermocouple measurement; use the wiring arrangement approved for the application.
-
How should an open-sensor indication on AAT141-S00 S2 be diagnosed?Check sensor continuity, cable joints, terminal seating and the configured channel type.
-
Can a millivolt channel on AAT141-S00 S2 be treated as a current input?No. The documented choices are thermocouple and specified millivolt ranges, not a general 4–20 mA input.
-
What timing should be considered for alarms sourced through AAT141-S00 S2?The reference data update is one second; include the configured filtering and process response in alarm design.
-
What must be transferred when replacing AAT141-S00 S2?Preserve each channel type, range, cold-junction arrangement, alarm limits and relevant calibration settings.
