The Allen-Bradley 1791D-8B8P is a combination I/O module from the CompactBlock I/O 1791D series, featuring 8 sinking inputs and 8 sourcing outputs. It can function as a base module hosting expansion input or output modules, or operate independently, supporting up to 32 total I/O channels—either 24 inputs and 8 outputs or 8 inputs and 24 outputs. The module operates at temperatures from 0 to 60°C, can be stored at -40 to 85°C, and has an IP20 environmental protection rating, ensuring reliable performance in industrial settings. In North America, Europe, and Asia, the 1791D-8B8P may possibly enhance combination module flexibility and could potentially be deployed across the globe, making it an essential component for professional industrial automation and DeviceNet integration.
