Electrical control panel equipment8/25/2023 DIN rail: Basic construction and versions () The original concept was developed and implemented in Germany in 1928, and was elaborated into the present standards in the 1950s. The fingers have rounded edges to protect wires (and hands) from cuts and abrasions.ĭid you know? The term DIN rail derives from the original specifications published by Deutsches Institut für Normung (DIN) in Germany, which have since been adopted as European (EN) and international (IEC) standards. They typically have “fingers” on the sides that create slots for wires to be added, removed, or rerouted. Wire ducts are channels that guide and separate runs of wire and cable. They secure relay sockets, circuit breakers, terminal blocks, fuses - as well as small drives, industrial-communication devices, PLCs, and other controls. A DIN rail is a standardized metal rail used for mounting components inside control panels and other electrical enclosures. Step Two: Back Panel Layout This is where the electric panel design begins to come to life.įollowing the plan, lines and drill holes are drawn on the back plate marking the location where components, including the wire ducts and DIN rails, will be mounted.ĭIN rails and wire ducts are like the bones of a control panel – everything is connected to them in one way or another. The assigned project manager will then source the specified components and enclosures in preparation for the next step of the panel build – layout of the back panel. Once the drawings are received by Simplex, they are reviewed, and adjustments (if any) are made. Occasionally, minor adjustments may need to be made to the original design. In order to ensure that all applicable regulations, UL standards, and safety requirements are met the design process can be quite complex. These devices can include air conditioners, heat exchangers, Vortex coolers, thermoelectric coolers, fans, and vents. Components must be spaced to allow “breathing room.” Devices to vent heat and cool the interior of the enclosure are also a crucial part of panel design. Enclosed electronics generate heat that can lead to component failure if not mitigated properly. Thermal management is another key factor to consider in panel design.
