Controllers & CPUs

Our comprehensive inventory of high-performance industrial controllers and CPUs provides the foundational processing power required for complex distributed control systems (DCS) and programmable logic controllers (PLC). We specialize in sourcing mission-critical components, including the Allen-Bradley ControlLogix 1756 series, Siemens SIMATIC S7-1500, and ABB AC800M processors. These units manage real-time logic execution and high-speed data processing across diverse fieldbus protocols. Our selection features high-availability modules like the Honeywell Experion C300 and Bently Nevada 3500/22 system monitors, engineered for demanding environments with robust thermal management and integrated diagnostics. Whether you are replacing a legacy Schneider Modicon CPU or scaling a modern Yokogawa Centum rack, our rigorously inspected hardware ensures precise timing and synchronization. We provide stable, low-latency control solutions to minimize unplanned downtime in large-scale process plant operations.
