Function and Working Principle
The AET4D-06 operates as a passive thermocouple signal termination interface between field sensors and DCS input modules.
Its working process includes:
- Receiving low-voltage thermocouple signals from field devices
- Organizing multi-channel wiring into structured terminal points
- Routing signals to Yokogawa analog input modules
- Supporting cold junction compensation via system-level processing
- Maintaining signal stability with low noise interference
Because thermocouples generate millivolt-level signals, the terminal board plays a key role in preserving signal integrity before conversion.
