About Block I/O
Allen-Bradley 1791 Block I/O combines I/O points and a communication adapter in one compact housing for distributed installations. We stock a range of 1791 blocks in AC, DC, and relay versions, including the 1791-16AC, 1791-16BC, 1791-8AC, and 1791-8BR. These blocks are long discontinued, so surplus units are often the only direct replacement. Every part ships with the Replace Industrial 2-year warranty.
