The 1783-BMS20CA module is specifically designed for analog input/output (I/O) applications. It provides 20 channels of combined analog inputs and outputs. Each channel can be individually configured as either an analog input or an analog output.

The module supports a wide range of input and output types, including voltage, current, thermocouples, and resistance temperature detectors (RTDs). It offers high-resolution analog input and output capabilities, allowing for precise measurement and control of analog signals.

The 1783-BMS20CA module is commonly used in industrial automation applications where analog signals need to be monitored or controlled. It integrates seamlessly with the ControlLogix platform, allowing for easy configuration, programming, and integration into a larger control system.
