Allen-Bradley 8500-XI0C I Ring Adapter Module is an I/O Ring Adapter within the 8500-series designed to interface 1771 I/O Ring devices with an AB controller. As a ring adapter, the module provides Receiver and Transmitter functionality and supports Remote Reset to recover from faults in the ring topology. It includes diagnostics for Active Adapter Fault and I/O Ring Fault, helping you quickly identify problems in the ring network. Used in legacy AB architectures to extend I/O around the ring with 1771 devices, it enables distributed I/O in 8500 ecosystems.
