The Allen-Bradley 1791-OB32 is a DC output block module from the Rockwell Automation 1791 Block I/O series, designed to provide 32 discrete output channels for industrial automation systems. This module is internally fused for circuit protection and includes labeling for clear identification and specification reference. The 1791-OB32 is recommended to be mounted vertically for optimal airflow, though it can also be installed horizontally with sufficient ventilation to ensure proper air-cooling. Engineered for durability and reliability, this DC output block offers efficient signal control and easy integration within distributed I/O architectures.
