Vision 230/260/280 User Guide
Two types of I/O modules are compatible with Vision OPLCs. I/O modules are available in a
variety of models. Snap-in I/O Modules plug directly into the back of a Vision OPLC,
creating a self-contained PLC unit with a local I/O configuration. I/O Expansion Modules
can also be easily integrated to greatly extend the system's control capacity.
These features combine to offer a cost-effective solution for medium-sized industrial
applications that require both an operator's interface and the ability to control small-to-
medium processes according to time and ambient conditions.
