Allen-Bradley 1791-16AC Block I Module 16 In 16 Out 120V AC

Allen-Bradley 1791-16AC Block I/O Module is a compact 32-point discrete I/O block designed for Rockwell Automation Remote I/O systems, delivering 16 inputs and 16 outputs at 120V AC. Inputs are organized in two banks of eight, with an on-state voltage range of 79–132V AC at 47–63 Hz and a nominal input current of 11 mA; off-state voltage must not exceed 35 V. On-state input current ranges from a 5 mA minimum to a 12.3 mA maximum at 132 V AC. The 16 outputs switch 120V AC loads, enabling direct control of AC devices from the same module. This Series B block I/O module integrates into 1791 Block I/O configurations over Rockwell’s Remote I/O networks, consolidating AC input and output channels into a single 16×16 footprint for streamlined wiring and panel space.
