Allen Bradley

Allen-Bradley automation hardware includes PLC controllers, chassis-based processors, distributed I/O, communication modules, power supplies and operator-control components. The architecture varies by family but commonly uses modular racks or compact controller platforms connected to local and remote I/O over industrial networks. ControlLogix, CompactLogix, PLC-5 and SLC 500 hardware can combine processors, discrete and analog I/O, specialty modules and network interfaces to build scalable control systems. Technical functions include logic execution, field-signal acquisition, output control, motion or process integration, diagnostics and data exchange between controllers and plant networks. This collection organizes Allen-Bradley parts used for maintenance, system expansion and replacement across multiple Rockwell Automation generations and form factors.
