Core Technical Specifications of the Yokogawa AAT145-S00 Module
The Yokogawa AAT145-S00 handles thermocouple and millivolt signals with high accuracy. This module provides 8 isolated input channels for simultaneous temperature measurements. Each channel accepts types B, E, J, K, N, R, S, and T thermocouples. You can also configure any channel for ±10 mV, ±50 mV, or ±100 mV ranges. The device achieves 20-bit resolution for fine temperature readings. A built-in cold junction compensator eliminates external reference needs. This design reduces wiring complexity and installation time.
