PLC Expansion Modules
Flexible I/O Solutions for Scalable and Reliable Automation
General Information
We supply a comprehensive range of PLC Expansion Modules, including both original and compatible units from globally recognized brands such as Siemens and Rockwell Automation. These modules allow for the flexible extension of input/output (I/O) capacity in modular PLC systems, adapting easily to specific application needs without redesigning the entire control architecture.
Designed for seamless integration, our PLC expansion modules include digital, analog, communication, and specialty I/O types. They support standard industrial communication protocols like Profibus, Modbus, and Ethernet/IP, and are suitable for harsh environments with high electromagnetic interference, vibration, or temperature variation.
We offer support in selecting compatible expansion modules for legacy systems, OEM replacements, and new installations. All models are available for worldwide shipping and backed by expert technical assistance for configuration and commissioning.
