Expansion Modules S7-200 PLCs are expandable by adding expansion modules.
Expansion modules with inputs and/or outputs are connected
to the base unit using a ribbon connector.
The ribbon connector is protected by a cover on the base unit.
Side-by-side mounting completely encloses and protects the
ribbon connector.
Mounting S7-200 PLCs can be mounted in one of two ways. A DIN clip
allows installation on a standard
DIN rail. The DIN clip snaps
open to allow installation and snaps closed to secure the
unit on the rail. The S7-200 can also be panel mounted using
installation holes located behind the access covers.
