Conair Group replaced centralized programmable-logic control on its resin loaders with a flexible distributed input/output system from Schneider Electric, according to Schneider of North Andover, Mass.
The move reduced wiring and installation costs to produce the machinery at Conair's factory in Franklin, Pa.
Before making the switch, Conair located the central plc in an area to minimize wiring between the plc and the customer's loaders. Even so, the system needed a lot of wiring, since loaders usually require five or six inputs and four or five outputs.
Schneider's Momentum controllers consists of three modules — an I/O base, a processor adapter and a communications adapter.
