The Allen-Bradley 1791D-0B8P is a base output module from the CompactBlock I/O 1791D series, featuring 8 outputs. It can be connected to expansion input or output modules to increase the number of I/O devices and adjust byte production and consumption. When paired with a 16-channel expansion output module, it provides a total of 24 outputs, while a 16-channel expansion input module results in 8 outputs and 16 inputs. The module produces 0 input bytes and consumes 1 output byte on its own, 1 input byte and 3 output bytes with an expansion output module, and 3 input bytes and 1 output byte with an expansion input module. In North America, Europe, and Asia, the 1791D-0B8P may possibly enhance I/O module scalability and could potentially be deployed across the globe, making it an essential component for professional industrial automation and DeviceNet connectivity.
