Panel PCs & Box PCs

Panel PCs and box PCs are industrial-grade computing platforms built for continuous operation in factory and process environments, combining processing hardware with rugged enclosures rated for temperature variation, vibration, and electrical noise. PLC Direct supplies panel PCs and box PCs as an independent supplier, carrying surplus sealed, refurbished, and used hardware for maintenance and replacement in installed industrial PC environments.

Where Are Panel PCs and Box PCs Used in Industrial Environments?

Panel PCs and box PCs are used wherever an industrial application requires a full computing platform integrated into a machine, control cabinet, or production environment rather than a general-purpose office computer. These platforms serve as operator interfaces, local SCADA clients, machine controllers, and data acquisition nodes across a wide range of industries.

Facilities and operations that depend on panel PCs and box PCs include:

Discrete manufacturing plants running machine-level visualization, recipe management, and process monitoring at the line.
Automotive and assembly operations using panel PCs as operator interface and data collection nodes on production equipment.
Food and beverage processing facilities requiring washdown-adjacent or sealed enclosure computing platforms.
Water and wastewater treatment plants operating panel PCs as local SCADA display and control hardware at pump stations and treatment facilities.
Oil and gas and chemical processing facilities using box PCs for data acquisition, historian functions, and process visualization in control rooms.

Replacement panel PCs and box PCs are a frequent maintenance requirement in aging automation environments where original hardware has reached end-of-life, but the surrounding control architecture remains operational.

What Should You Know Before Ordering Panel PCs and Box PCs?

Hardware condition options: PLC Direct supplies panel PCs and box PCs in surplus sealed, refurbished, and used condition. Surplus sealed units are factory-sealed stock that has not been previously installed; refurbished units have been inspected and tested to confirm operational functionality; used hardware is sourced from decommissioned systems and suits facilities managing lifecycle replacements under budget constraints.

Compatibility and part identification: Panel PCs and box PCs are identified by full part numbers that encode the display size, processor variant, memory configuration, and operating system for panel PC models, and the processor, I/O interface, and form factor for box PC models. For Siemens SIMATIC IPC hardware, the 6AV or 6ES prefix and the model designation together define the hardware generation and configuration. Confirm the part number from the existing unit's label or system documentation before ordering to ensure the replacement matches the installed hardware specification.

Warranty: All panel PC and box PC hardware purchased from PLC Direct carries a standard 1-year PLC Direct warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.

PLC Direct supplies panel PC and box PC hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.

Frequently Asked Questions

A panel PC integrates a display, touchscreen, and computing hardware into a single, front-panel-mounted unit designed for operator interface and machine-monitoring applications. A box PC is a standalone computing unit without an integrated display, typically mounted in a control cabinet or rack and connected to a separate monitor or HMI, suited for data acquisition, historian, and background processing applications.

Industrial panel PCs and box PCs are designed for 24/7 operation under factory conditions, including vibration, temperature extremes, and electrical noise, with features such as fanless cooling, wide-voltage DC power inputs, and conformal-coated boards that standard office computers do not offer. Replacement hardware should match the installed unit's form factor, mounting configuration, display interface, and I/O specification to avoid integration issues with the surrounding control system.

PLC Direct stocks panel PCs and box PCs from Siemens and Beckhoff, including SIMATIC IPC panel PC and box PC hardware across multiple generations, as well as Beckhoff CX series embedded PC platforms. B&R Power Panel and Industrial PC hardware are also stocked. Contact PLC Direct with your part number to confirm current availability.

PLC Direct supplies panel PCs and box PCs as surplus sealed, refurbished, and used hardware. Surplus sealed units are factory-sealed and have not been previously installed; refurbished units have been inspected and tested to operational condition; used hardware is sourced from decommissioned systems for facilities managing replacement budgets on older installations.

Match the full part number from the existing unit's label or system documentation, confirming the display size, processor configuration, memory, and I/O interfaces match the installed hardware. For Siemens SIMATIC IPC models, the 6AV or 6ES article number encodes all configuration details and is the most reliable identification reference.
