Schneider 140NOL91100 Logic Controller Module

The Schneider Electric 140NOL91100 is a high-reliability logic controller module designed for use within the Modicon Quantum series of programmable automation controllers. Specifically engineered to execute logic tasks at the I/O or communication level, this module operates as a local logic decision-maker rather than a full CPU. It is commonly referred to as a logic coprocessor or application-specific logic module that enhances the processing capacity of Quantum systems in distributed or modular configurations.

Its role is to offload processing tasks from the main CPU, manage time-critical functions locally, and increase the overall responsiveness of the automation system. Ideal for complex industrial environments, the 140NOL91100 is seamlessly integrated with other Quantum modules via the local backplane bus, providing deterministic behavior and support for custom logic execution.

This makes it a valuable asset for facilities requiring modularity, speed, and distributed control—such as manufacturing, petrochemical, power generation, and infrastructure systems.
