Yokogawa AAT141-S00 CENTUM VP TC/mV Input Module (16-channel, Isolated)

Description

The Yokogawa AAT141-S00 is a 16-channel isolated thermocouple and millivolt input module designed for FIO systems within CENTUM VP field control stations. It functions as a signal converter by inputting field temperature and voltage signals into internal data for the Field Control Station (FCS). The AAT141-S00 module receives signals from thermocouple types J, K, E, B, R, S, T, and N, as well as mV voltage spans ranging from -100 to 150 mV and -20 to 80 mV. It supports dual-redundant configuration and connects externally via a pressure clamp terminal block.

Features

• 16 isolated input channels for thermocouple and mV signals.
• Software-selectable TC/mV input types individually configured for CH1 to CH16.
• Dual-redundant configuration capability.
• Dedicated pressure clamp terminal external connection interface.
• Software-configurable burnout detection (UP/DOWN/Not available) for all channels.

Applications

• Process temperature monitoring using thermocouples.
• Millivolt analog input signal interfacing in CENTUM VP FIO DCS environments.
• High-reliability industrial control systems requiring isolated I/O modules.

Installation Guidelines

• Use a non-ground type thermocouple (TC) because the device is an isolated type module; using ground type TC on multiple channels causes temperature errors due to multi-point ground.
• Ensure proper installation onto supported ESB, Optical ESB, or ER bus node units.
• Maintain matching wiring resistance for signal cables to ensure measurement accuracy.
