PLC Communication Modules

PLC communication modules allow programmable logic controllers to communicate with industrial networks, remote I/O systems, and other automation devices within a control system. These modules enable data exchange between controllers, HMIs, drives, sensors, and industrial networking equipment used in modern manufacturing environments.

PLG Automation supplies PLC communication modules from major industrial automation manufacturers including Allen-Bradley, Siemens, Schneider Electric, Mitsubishi, Omron, ABB, GE Fanuc, Eaton, and Square D. Our inventory includes Ethernet communication modules, industrial network interfaces, and fieldbus communication processors used in a wide range of PLC platforms.

Maintenance engineers and system integrators frequently source spare PLC communication modules when upgrading industrial networks, replacing failed interface cards, or maintaining compatibility with existing automation infrastructure. These modules are commonly used in platforms such as Allen-Bradley ControlLogix and SLC systems, Siemens SIMATIC PLC networks, Schneider Modicon controllers, Mitsubishi MELSEC automation platforms, Omron SYSMAC systems, ABB automation systems, and GE Fanuc PLC hardware.

PLG Automation provides fast RFQ support and sourcing for PLC communication modules used in industrial automation systems. If a specific communication module cannot be located on our website, our team can often help locate surplus or discontinued industrial networking hardware.
