PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1791-N4V2 is an analog I/O Module belonging to the Block I/O 1791 series. This unit features four analog inputs designed to accept both current and voltage signals from connected field instrumentation. It provides four analog voltage outputs operating across a bipolar range of -10 to 10 volts. Operating power requires a 120V AC nominal power supply line. Integrated LED status indicators give direct diagnostic feedback on operational states.
Engineers mount this block assembly directly to enclosures using two dedicated mounting holes tailored for 1/4-inch screws. Wiring connections attach via a removable terminal strip that simplifies installation and maintenance workflows. The module weighs approximately 1.31 lbs (0.60 kg) for panel installations. Integrated current and voltage capabilities permit straightforward consolidation of distributed process points within automation panels.
