Allen Bradley T9110 Processor Module

Overview

The T9110 Processor Module is the central unit in the AADvance controller, responsible for executing application logic, safety functions, and communication tasks. It interfaces with I/O modules, handles diagnostics, and communicates with external systems. With dual redundant power supplies, robust isolation, and fault-tolerant architecture, it ensures reliable operation in demanding industrial environments. It supports Ethernet and serial communications, along with periodic self-diagnostics to maintain high performance and safety.
