PLC Racks & Enclosures

PLC racks are the simple components that hold everything together within a programmable logic controller. They're available in different sizes to suit the specific needs of a controller, and to hold more modules if needed.

How do PLC racks work?

PLC racks have a backplane at the rear that let the cards communicate with the CPU (central processing unit). A PLC rack can take many different types of I/O modules that just slide into the rack and plug in. A power supply is connected into the rack, feeding power to the modules that are plugged into the rack. Once you remove all modules you're left only with the power supply and the PLC rack.

Types of PLC racks

PLCs feature in devices that can be small enough to fit in your pocket, or industrially sized. Therefore some PLCs will need larger PLC racks with greater capacity. Variations between PLC racks include different backplane currents, widths, lengths and number of module slots.
