The Allen-Bradley 1791D-16B0 is a base input module from the CompactBlock I/O 1791D series, featuring 16 sinking inputs. It includes a DeviceNet I/O adapter and a built-in power supply, providing reliable connectivity and operation within industrial automation systems. On its own, the module produces 2 input bytes, while connection to an expansion input module increases production to 5 input bytes, and connection to an expansion output module results in 3 input bytes. In North America, Europe, and Asia, the 1791D-16B0 may possibly enhance input module performance and could potentially be deployed across the globe, making it an essential component for professional industrial automation and DeviceNet integration.
