Collection: Allen-Bradley PLC-5

The industrial workhorse that defined an era. Allen-Bradley PLC-5 controllers brought modular flexibility and high-speed processing to large-scale automation when reliability was everything - and they're still running critical systems decades later. With support for DH+, Remote I/O, and Ethernet/IP communication, these PLCs orchestrate complex control sequences across manufacturing plants, oil & gas facilities, and utilities where downtime isn't an option. Programmed with RSLogix 5 software, the PLC-5 delivers robust monitoring and control capabilities through its modular architecture, allowing you to scale I/O and processing power as your application demands. While newer platforms have emerged, countless PLC-5 systems continue proving their worth in mission-critical installations worldwide.
