The Allen-Bradley 1794-ASB is a robust FLEX I/O adapter module designed to seamlessly connect FLEX I/O modules to a Remote I/O (RIO) communication network. This adapter acts as a bridge, allowing a scanner, such as a PLC-5 or SLC 5/04 processor, to control and monitor up to eight digital or analog I/O modules from a remote location. It supports multiple communication rates, which are easily configured via onboard switches, making it a versatile solution for distributed I/O applications. The 1794-ASB is renowned for its reliability and ease of integration into existing Allen-Bradley control systems, providing a cost-effective way to expand system capabilities.
