DSRF180A 57310255-AV analog input board is an electronic device mainly used to connect and collect analog signals from external sensors, such as voltage or current signals, and convert these analog signals into digital signals for analysis and processing by the control system. =Another analog input board, IS200VAICH1CBA, can provide 20 analog inputs and 4 outputs, which are equally distributed between the two terminal boards. It is mainly used in gas turbine control systems, usually using cables to connect the terminal board to the VME rack where the card is located. The board is capable of use with TMR (Triple Modular Redundancy) or Simplex functionality and requires another circuit board (TBAIHIB or earlier) for proper operation. Please note that different analog input boards have different functions and features, and specific parameters and performance may vary depending on product model and manufacturer. Therefore, when selecting and using an analog input board, it is recommended to select based on specific application needs and system requirements, and to refer to the technical documentation and guidelines provided by the manufacturer for operation and configuration.
