maintenance purposes led to the adoption of the DIN rail mounting format. DIN rail enclosures are available in various sizes and offer quick, convenient, and standardised mounting for a wide range of control systems. However, despite DIN rail’s many advantages, individual enclosures may still stipulate minimum separation distances to allow for adequate heat dissipation and airflow. Placing more electronic components within a given DIN rail enclosure has led engineers to be more creative with PCB layout, often adopting a motherboard or backplane PCB that accommodates sub-system ‘daughter’ boards. This approach increases the density of electronic systems within a given space, subject to potential thermal management requirements, allowing increased system functionality.
