A Remote baseplate cannot stand alone. It must be connected to a system that has a CPU. The CPU can be in a PLC or in a Personal Computer that is equipped with a Personal Computer Interface Card.Remote capability is facilitated by the Remote baseplate’s built-in isolation between the +5 volt logic supply used by the I/O modules residing in the Remote baseplate and the supply for the interface circuit associated with the I/O Bus Expansion Interface. Isolation helps prevent problems associated with unbalanced ground conditions.Each remote baseplate has a 25-pin female D-type Expansion connector mounted at its right end for connection to other baseplates.Remote baseplates are the same physical size, use the same type power supplies, and support the same I/O and option modules as the Expansion baseplates.Each Remote baseplate has a Rack Number Selection DIP switch.
