Surplus electrical and control components for industrial automation and CNC systems, including servo drives, PLCs, power supplies, and I/O modules. All inventory is in stock and available for immediate shipment.

What Are Electrical & Control Components?

Electrical and control components are the core systems that keep CNC machines and automated production lines operating. Drives convert control signals into precise motor motion. Control modules execute the programs that govern machine behavior. Power supplies regulate voltage across the system. I/O modules connect control systems to physical equipment, while sensors provide real-time process feedback. When any of these components fail, production stops.

Available Electrical & Control Inventory

MRO Exchange maintains a deep, rotating inventory of surplus electrical and control components across CNC and industrial automation applications. With over 500 components currently in stock, our selection includes servo drives, spindle amplifiers, VFDs, CNC control modules, PLCs, HMI panels, MPGs, contactors, circuit breakers, power supplies, encoders, I/O modules, and sensors. Inventory is heavily focused on Fanuc systems, with strong representation from Siemens, Mitsubishi, and Allen-Bradley.

Why Buy Surplus Electrical Components?

New OEM electrical components for older CNC and automation platforms are often difficult to source quickly and cost-effectively. Manufacturers discontinue legacy product lines, and lead times for new components can stretch weeks or months. Surplus components sourced from decommissioned equipment and system upgrades offer a faster and more cost-effective alternative, often available at a fraction of new OEM pricing.

Fanuc Electrical Components

MRO Exchange stocks a large selection of surplus Fanuc electrical and control components, including servo drives, spindle amplifiers, CNC control modules, I/O modules, power supplies, and operator panels. Fanuc systems represent the largest installed base in North American manufacturing, making replacement components consistently in demand.

Sourcing Parts for Older CNC Machines

Maintaining older CNC machines with surplus electrical components is often the most cost-effective approach. Machines that are fully depreciated can continue producing at full capacity, and sourcing replacement components from surplus inventory helps extend their operational life without the cost of new OEM parts.
