PLC Configuration
©snaim 2008
The configuration of PLC refers to the packaging of the components.
Typical configurations are listed below from largest to smallest.
� Rack Type : A rack can often be as large as 18” by 30” by 10”
� Mini: These are similar in function to PLC racks, but about the half size.
Dedicated Backplanes can be used to support the cards OR DIN rail
mountable with incorporated I/O bus in module.
� Shoebox: A compact, all-in-one unit that has limited expansion
capabilities. Lower cost and compactness make these ideal for small
applications. DIN rail mountable.
� Micro: These units can be as small as a deck of cards. They tend to have
fixed quantities of I/O and limited abilities, but costs will be lowest. DIN
rail mountable.
Sizing of PLC
