The Allen-Bradley 1791-IOVW is a Block I/O module from the Rockwell Automation 1791 series, designed for efficient distributed control in industrial automation systems. It features 32 sourcing inputs and 32 sinking outputs, operating at 24 volts DC with an integrated power supply and a programmable controller interface. Similar to the 1791-IOBW model but with different input and output configurations, the 1791-IOVW module is engineered for reliable performance and easy system integration. For optimal ventilation and heat dissipation, it should be mounted horizontally with at least 2 inches of clearance from adjacent modules.
