The Allen-Bradley 1791-24A8 Block I/O Module is a 32-point AC I/O block for Allen-Bradley Remote I/O networks, delivering 24 input points and 8 output points at 120 VAC. Designed for use in 1791 Block I/O installations, the module mounts in a remote I/O rack and can be oriented vertically or horizontally. It communicates with a compatible controller over the 1791 Remote I/O bus to provide deterministic discrete I/O for sensing and controlling field devices. Typical applications include wiring sensors and actuators across manufacturing equipment, where 24 inputs monitor devices and 8 outputs drive actuators.
