Allen-Bradley Modular PLCs (ControlLogix & CompactLogix)
Allen-Bradley modular PLC platforms are widely used in industrial automation systems where scalable control, flexible I/O expansion, and reliable industrial networking are required. Modular architectures allow you to build or expand control systems using interchangeable processors, communication modules, chassis hardware, and I/O modules—ideal for OEM equipment, packaging lines, manufacturing cells, and process control.
This category includes refurbished modular PLC components used for maintenance replacement, upgrades, and system expansion. If you are working with an existing Rockwell/Allen‑Bradley system, selecting the correct platform family helps ensure compatibility with your controller, rack, and network architecture.
Common modular PLC module types
- Processors and controller modules
- Digital and analog I/O modules
- Communication modules (EtherNet/IP, ControlNet, etc.)
- Chassis, power supplies, and accessories
