Yokogawa AAT145-S00 Thermocouple and Millivolt Input Module

Product Description

The Yokogawa AAT145-S00, based on the AAT145 thermocouple and millivolt input module, acquires low-level analog signals for process monitoring within compatible Yokogawa distributed control system architectures. It accepts thermocouple or millivolt inputs for temperature and voltage measurement. Channel configuration, terminal-board compatibility, and cold junction compensation requirements must be verified against the applicable hardware documentation.

Hardware Specifications

Thermocouple Input and Cold Junction Compensation

Thermocouples generate a low-level voltage related to the temperature difference between the measuring junction and the reference junction. The input system must account for the reference-junction temperature to calculate the measured temperature correctly.

Before commissioning, verify the configured thermocouple type, input range, reference-junction compensation method, and sensor wiring polarity. Millivolt measurements require the corresponding input configuration and suitable low-noise wiring.

Channel isolation and terminal-board compatibility should be confirmed using the manufacturer's documentation for the exact hardware configuration. The supplied data does not establish isolation ratings or confirm the number of usable channels for every terminal-board arrangement.

Frequently Asked Questions (FAQ)

Q: Can the AAT145-S00 accept thermocouple and millivolt signals on the same module?

A: The supplied specifications describe thermocouple and millivolt input modes with channel-level selection. Confirm the permitted channel combinations and configuration procedure in the applicable Yokogawa hardware manual.

Q: What should be checked before connecting a thermocouple?

A: Verify the thermocouple type, lead polarity, configured input range, reference-junction compensation method, and terminal-board wiring. Use wiring appropriate for the thermocouple type and minimize electrical noise pickup.

Q: Are the module's power consumption and operating temperature specified?

A: These values are not provided in the supplied data. Obtain the applicable limits from the manufacturer's technical documentation before installation and cabinet thermal assessment.

Field Installation Guidelines

• Confirm the module part number and hardware revision against the system configuration before installation.
• Verify compatibility with the intended I/O carrier, terminal board, and control system.
• Isolate power according to site procedures before inserting, removing, or rewiring the module. Do not assume hot-swap capability without explicit manufacturer confirmation.
• Connect thermocouple extension or compensating cables of the appropriate type and maintain correct polarity.
• Separate low-level analog signal wiring from power conductors and high-noise switching circuits.
• Apply cable shielding and grounding according to the manufacturer's wiring instructions and the plant grounding design.
• Confirm the selected thermocouple or millivolt mode and verify channel readings during commissioning.
• Do not apply the stated +/- 5 V allowable input value as a universal operating range without checking the official hardware specifications.
