A PLC rack provides a physical structure to mount and organize PLC components such as the CPU, I/O modules, communication modules, and power supplies. It ensures proper electrical connections via a backplane and supports heat dissipation and modular expansion.
The number of slots determines the maximum number of I/O modules you can install. Count the modules you need for your application and select a rack with at least that many slots, considering future expansion. Typical racks offer 4 to 12 slots.
The backplane current rating is the maximum current the backplane can supply to all modules. It must exceed the total current draw of all installed modules to prevent overload. Ratings typically range from 10 to 20 A; verify your modules' requirements.
According to IEC 61131-2, typical racks operate in temperatures from -40 to 85 °C and humidity from 5% to 95% non-condensing. The degree of protection ranges from IP20 for cabinet mounting to IP54 for standalone use. Always confirm with the manufacturer for your specific model.
