Provides 15 thermocouple or millivolt input points.
01
Key Information
AAT145-S50 is a Yokogawa thermocouple/mV input module for CENTUM VP field control system I/O.
The module provides 15 individually isolated input points for thermocouple or millivolt signals.
Reference-junction performance depends on correct terminal-board selection and installation away from radiated heat sources.
02
Functions
Maintains individual isolation by input channel.
Uses the S50 standard execution identified by the complete model.
Works with the designated Yokogawa terminal arrangement and system engineering.

Heat-source placement reviewed
04
Installation
Confirm the approved terminal board, cable and thermocouple types for all 15 points.
Keep the terminal board away from radiated heat; use shielding if a heat source must be above, beside or below it.
Record channel type, polarity, range and cold-junction arrangement before transferring field wiring.
After installation, verify ambient reference behavior and test every channel at representative temperatures or mV values.
05
Lifecycle
Keep the AAT145-S50 module, terminal-board identity and channel schedule in one controlled record.
Inspect terminal tightness, shield routing and nearby heat sources during cabinet maintenance.
Retain channel calibration and reference-junction test results.
Do not substitute S51, SK or SM executions without checking system and environmental requirements.

FAQ
Why does terminal-board placement matter for AAT145-S50?
Radiated heat can disturb reference-junction compensation, so the terminal board must be protected from nearby heat sources.
What channel documentation should accompany AAT145-S50?
Provide all 15 channel tags, thermocouple types or mV ranges, polarity, terminal-board model and configured alarms.
Can AAT145-S50 be selected only from its 15-point count?
No. The S50 execution, isolation scheme, terminal hardware and system release must also match.
What is useful evidence when diagnosing an AAT145-S50 channel offset?
Record the field source, extension-wire type, terminal temperature, channel reading, reference measurement and nearby heat conditions.
How should AAT145-S50 be accepted after replacement?
Test each used channel across its working range and verify cold-junction behavior, polarity, alarms and system diagnostics.
