Product Overview
The Allen-Bradley 1791-32A0 is a discrete AC input block I/O module within the 1791 Block I/O platform, designed for distributed Remote I/O (RIO) architectures. It provides 32 120 VAC input channels grouped into four groups of eight, enabling direct connection of devices such as limit switches, selector switches, float or proximity switches. It features group-to-group and I/O-to-logic isolation, RIO communications, and operates in industrial control environments where localized input acquisition and segregation are required.
Best Suited For
- Remote I/O architecture with RIO control systems
- In-cabinet acquisition of 120 VAC discrete inputs (e.g. proximity, selector switches)
- Distributed input expansion in PLC-2, PLC-3, PLC-5 or SLC® 5/02 systems
- Applications requiring isolation between input groups and logic
