Core Functions and Roles
Signal Conditioning and Isolation:
This board is used to perform signal conditioning, isolation, and interfacing between field devices (such as sensors and actuators) and I/O modules.
It is responsible for transmitting and receiving critical input and output signals—including analog, digital, RTD, and thermocouple signals—ensuring precise and reliable operation of turbine systems.
Power Supply:
It provides a stable 24 VDC control-level power supply, typically used to power key components within the control cabinet, such as cooling fans.
It also supports AC/DC monitoring and motor excitation functions.
