This board is part of the main control unit of a textile machine. It communicates with the CPU188 board and is responsible for receiving control signals and safely transmitting them to various devices. The board features 16 digital outputs in relay and transistor configurations. All outputs are fully isolated (using high-speed optocouplers), enhancing system reliability and preventing fault propagation during errors.

Azonic, leveraging its technical expertise and experience, has reverse-engineered the 16-output board to fully match the original sample and offered it to local consumers.
