What Is a DIN Rail PC?

A DIN rail PC is an industrial computer designed to mount on a standard 35mm DIN rail, the same rail that holds circuit breakers, terminal blocks, and PLCs inside a control cabinet. DIN rail PCs are typically compact (less than 100mm wide), low power, and fanless, they integrate into the panel as naturally as any other rail-mount device.

What Is a Box PC?

A Box PC (fanless embedded computer) is a compact industrial computer housed in a rugged aluminium chassis. It mounts to a flat surface (wall, panel backplate, or enclosure) using screws or VESA-pattern holes, not on a DIN rail. Box PCs are generally larger than DIN rail units and offer more I/O and expansion capability.

DIN Rail PC vs Box PC Comparison

Feature	DIN Rail PC	Box PC
Mounting	35mm DIN rail (snap-in)	Surface mount (screws/VESA)
Size	Very compact (<100mm wide)	Compact to mid-size
I/O	Limited (2 a 4 COM, 2 a 4 USB)	More comprehensive
Installation time	Fast, snap on rail, connect cables	Requires drilling/mounting
Best for	Data loggers, IoT gateways, protocol converters	SCADA workstations, vision systems

Choose DIN Rail When:

Installing inside an existing control cabinet with DIN rail space
Running lightweight applications (data logging, protocol conversion, IoT gateway)
Minimising installation time and panel wiring

Choose Box PC When:

Running SCADA, MES, or vision applications requiring more CPU power
Need multiple COM ports, PCIe expansion, or more USB
Mounting outside a control cabinet (on a shelf, wall, or 19" rack)

Domande frequenti

A DIN rail PC clips onto the 35mm DIN rail inside a control cabinet, no cutout or special bracket required. A Box PC is a standalone unit typically panel-mounted, DIN-rail mounted (with adaptor), or desk-mounted separately. DIN rail PCs are more integrated into the cabinet infrastructure; Box PCs offer more expansion options and I/O.

Choose a DIN rail PC when you need to add computing capability inside an existing control cabinet with minimal modification, no panel cutouts, using existing 24V DIN rail power. Choose a Box PC when you need more expansion slots, higher performance processors, or when the computer will be mounted separately from the control cabinet.

Yes, both run Windows 10 IoT Enterprise LTSC or Linux and support the same industrial software stack (SCADA, OPC UA servers, protocol gateways, data loggers). The form factor difference is purely physical; both use standard x86 processors and connect to the same PLCs, sensors, and networks.

DIN rail PCs are compact (typically 150 a 200mm wide, 70 a 120mm tall, 80 a 110mm deep) and designed to fit between other DIN rail components. Box PCs vary from ultra-compact (120×90×35mm) to full-size (250×200×80mm) and are mounted with brackets or placed on a surface. DIN rail PCs are more space-constrained but require less mounting hardware.

Yes, TSL Automation Solutions carries both Avalue DIN rail embedded PCs and compact Box PCs. Our engineering team can recommend the right form factor based on your cabinet dimensions, power availability, I/O requirements, and mounting constraints. Contact our Mumbai office for a free consultation.
