Yokogawa AAT141-S00 TC/mV Input Module (Isolated)
Product Introduction
The Yokogawa AAT141-S00 is an isolated TC/mV input module designed to accurately convert thermocouple and millivolt signals into digital data for distributed control systems. Built for high signal integrity, this module features galvanic isolation between input channels and the bus, minimizing ground-loop interference. Its robust design ensures stable performance even in electrically noisy environments, making it a reliable choice for precise temperature and low-level voltage measurements in industrial processes.
Applications
The AAT141-S00 is deployed across a variety of industries and scenarios, including:
-
Chemical and Petrochemical Plants: Temperature monitoring in reactors, distillation columns, and heat exchangers.
-
Power Generation: Boiler and turbine temperature control for efficient power production.
-
Oil & Gas: Pipeline temperature measurement and safety monitoring in remote installations.
-
Food & Beverage: Precise thermal control during cooking, pasteurization, and sterilization processes.
-
Pharmaceutical Manufacturing: Validation of temperature profiles in critical production steps.
Advantages
-
Galvanic Isolation: Provides up to 2 kV isolation between input channels and bus, preventing ground-loop errors and enhancing safety.
-
High Accuracy: Typical accuracy better than ±0.1 % of span ensures reliable data for tight control loops.
-
Wide Input Range: Supports most common thermocouple types (K, J, T, E, N, R, S, B) and ±50 mV DC signals.
-
Fast Conversion: Update rate of 100 ms per channel allows responsive control and monitoring.
-
Compact Footprint: Slim module profile saves rack space while maintaining full functionality.
