DIN Rails

DIN Rail, short for Deutsche Institut für Normung rail, is a standardised mounting system widely used for securing industrial control equipment within racks, enclosures, and panels. This versatile mounting method provides a secure and organised platform for a variety of electrical and electronic components, such as circuit breakers, relays, power supplies, and terminal blocks.

The significance of DIN rail lies in its ability to streamline the installation and organisation of components in industrial control systems. By offering a standardised platform, DIN rail simplifies wiring, saves valuable space, and enhances the overall efficiency and maintainability of control panels.

DIN rails are also available in various types and sizes to accommodate different components and applications, with many conforming to European (EN) and international (IEC) standards to ensure compatibility.

Types of DIN Rail

There are four common DIN rail types that vary in length and size:

Top Hat DIN Rail

Top hat DIN rail, also known as TS35 rail or 35 mm DIN rail, is the most widely used type. Its name derives from its cross-section, which resembles a top hat. This DIN rail mount is prevalent in industrial control panels and automation systems due to its versatility and broad compatibility with various components.

The EN 50022 standard defines top hat DIN rails with depths of 7.5 mm and 15 mm, offering flexibility for different mounting needs. They are readily available and suitable for mounting a wide range of electrical and industrial control components, including circuit breakers, motor controllers, transformers, and more.

Miniature Top Hat DIN Rail

Miniature top hat DIN rail, also known as TS15 rail, is a smaller version of the standard top hat rail. Measuring 15 mm wide and 5.5 mm deep, it's ideal for applications where space is limited or smaller components are used. This DIN mount is commonly used to mount small components like compact junction boxes and relays in applications requiring a smaller footprint.

C-Section DIN Rail

C-section DIN rail, also known as TS-32 rail, features a C-shaped cross-section, providing a curved and symmetrical mounting surface. While an older standard, it is still used for larger or heavier components, such as power supplies and transformers, due to the excellent wall support it provides.

C-section DIN rails are categorised by their height, with common variants including C20, C30, C40, and C50. However, some modern components may require adapters for secure mounting on this type of rail.

G-Section DIN Rail

G-section DIN rail has a G-shaped cross-section with an asymmetrical design. This unique shape is often used in specific applications where the asymmetrical profile offers advantages in mounting or component placement. The deeper channel on one side of the rail provides extra support for heavier or higher-powered components.

Key Features of a DIN Rail Mount

DIN rail mounting systems offer a range of features that contribute to their widespread use in industrial and electrical applications:

• Standardised Design: DIN rails adhere to specific dimensions and standards (EN/IEC), ensuring compatibility with a wide range of components and enclosures. This standardisation simplifies design and installation processes.
• Ease of Installation: Components designed for DIN rail mounting can be easily snapped or slid onto the rail, eliminating the need for individual panel mounting and saving significant installation time.
• Secure Mounting: The design of DIN rails provides a secure and stable platform for mounting components, even in environments subject to vibrations or movement. This ensures the reliability and longevity of electrical connections.
• Space Optimisation: DIN rails facilitate efficient use of space within enclosures by allowing components to be mounted closely together in a compact and organised manner.
• Versatility: DIN rails support a wide variety of components, including terminal blocks (for connecting electrical wires), end caps/separators (for organising and isolating components), and jumpers (for bridging connections between terminal blocks).
• Safety and Accessibility: The organised layout of components on a DIN rail promotes better accessibility for maintenance and troubleshooting, contributing to overall safety and ease of use.

Industrial Applications of Din Rails

DIN rails are versatile mounting solutions used across a wide range of industries and applications.

Industrial Automation

DIN rails are extensively used in industrial automation, providing a structured framework for mounting programmable logic controllers (PLCs), sensors, relays, and other automation components. This organised approach simplifies wiring, improves system reliability, and facilitates efficient maintenance.

Electrical Panels and Control Cabinets

DIN rails are commonly found in electrical panels and control cabinets, where they provide a secure and organised method for mounting circuit breakers, terminal blocks, and other electrical devices. This simplifies panel assembly, enhances wiring organisation, and improves overall safety.

Renewable Energy Systems

Renewable energy systems, such as solar and wind power installations, utilise DIN rails to support inverters, charge controllers, and monitoring equipment. This ensures efficient and reliable power generation by providing a stable and organised platform for critical components.

Home Automation

DIN rails are not limited to industrial settings; they also find applications in home automation. They can be used to mount smart home devices, control modules, and other components, providing a neat and organised solution for managing home automation systems.

Other Applications

In addition to the above, DIN rails are also used in various other applications, including:

• Telecommunications: Mounting network switches, routers, and other telecommunications equipment.
• Transportation: Used in railway signalling systems, automotive control panels, and aerospace applications.
• HVAC Systems: Mounting thermostats, control modules, and other components in heating, ventilation, and air conditioning systems.
• Lighting Control: Used in lighting control panels for mounting relays, dimmers, and other lighting control devices.

How to Choose the Suitable DIN Rail

Selecting the appropriate DIN rail for your application requires careful consideration of several factors:

• Component Compatibility: Understand the dimensions and mounting requirements of the electrical components you plan to install on the DIN rail. Ensure the rail's width and depth are sufficient to accommodate the components and any associated wiring or accessories.
• DIN Rail Dimensions: Refer to a DIN rail size chart to determine the appropriate width and length for your needs. Consider the available space within your enclosure and choose a rail that fits comfortably without overcrowding.
• Installation Space: Account for the space required for installation, including clearances for wiring and access to components. Ensure adequate space for proper ventilation and heat dissipation.
• Material and Finish: Consider the material and finish of the DIN rail, such as zinc-plated steel or aluminium, based on the environmental conditions and application requirements.
• Standards Compliance: Ensure the DIN rail complies with relevant EN or IEC standards to guarantee compatibility with your components and enclosures.
