What is a Din Rail Mount Computer?
A din rail mount computer is an industrial PC designed to clip directly onto standard DIN rails (typically 35mm) found inside electrical cabinets and control panels. Unlike conventional desktop PCs that sit on a desk or in a rack, these rugged, space-saving computers are built for 24/7 operation in harsh factory floor environments. They eliminate the need for separate mounting shelves, making them ideal for automation, process control, and edge computing where real estate inside a cabinet is at a premium.
Key Specifications and Technical Details
Industrial din rail computers are engineered for reliability and longevity. Key specifications include:
-
Fanless Cooling: Passive thermal design with no moving parts, reducing dust ingress and mechanical failure.
-
Wide Power Input: Typically 6V to 36V DC with surge protection (e.g., up to 80V/1ms) to handle unstable power in industrial settings.
-
Extended Temperature Range: Operation from -20°C to 60°C or wider, suitable for unventilated cabinets.
-
Compact Dimensions: Typical footprint around 56×107×153 mm (W×D×H) and weight under 1 kg.
-
Rich I/O: Multiple COM ports (RS-232/422/485), Gigabit Ethernet, USB, and optional isolated digital I/O for connecting to PLCs, sensors, and actuators.
Use Cases and Applications
Din rail computers are deployed across a wide range of automation scenarios:
-
PLC and SCADA Integration: Running logic controllers or HMI/SCADA software directly on the rail.
-
Edge Computing: Processing sensor data locally before sending aggregated information to the cloud.
-
Machine Vision: Powering inspection cameras and running image processing algorithms.
-
Building Automation: Controlling HVAC, lighting, and security systems within a cabinet.
-
Transportation: In-vehicle or trackside computing for traffic control and telematics.
Comparison: Din Rail vs. Standard Mini PC for Automation
| Feature | Din Rail Computer | Standard Mini PC |
|---|---|---|
| Mounting | Clips onto 35mm DIN rail | Requires shelf or bracket |
| Cooling | Fanless (passive) | Often fan-cooled |
| Power Input | Wide DC range (6-36V) | Fixed DC (12V or 19V) |
| Operating Temp | -20°C to 60°C | 0°C to 40°C |
| Vibration Resistance | High (secured to rail) | Low |
| Typical Lifespan | 5-10 years | 3-5 years |
Thinvent's Industrial Din Rail Computers
Thinvent offers a range of industrial PCs specifically engineered for DIN rail mounting in automation environments. Our models, such as the IPC series, feature fanless designs, wide input voltage support (12V DC), and rugged chassis that withstand vibration and temperature extremes. Processors range from energy-efficient Intel N100 (4 cores) to high-performance Intel Core i5-1240P (12 cores), allowing you to match computing power to your application—from simple data logging to advanced edge AI. All units are validated for 24/7 operation inside control cabinets and come with flexible mounting kits for standard 35mm DIN rails.
