Barber-Colman 40BA-211BC-CC0-A-00 PLC Chassis

Barber Colman 40BA-211BC-CC0-A-00 PLC Chassis is a 12-slot card rack motherboard designed for the Barber Colman MACO 4000 injection-control system. The unit is described in retailer and surplus listings as a 12-Slot Card Rack Motherboard, indicating it serves as the primary chassis to mount MACO 4000 control cards within a control cabinet. The MACO 4000 injection-control lineage is associated with Barber Colman, a brand that later became part of Invensys/Rockwell, and this chassis appears among other MACO backplanes in catalogs and marketplaces. With twelve slots, the unit provides capacity for a range of modular cards that implement the MACO 4000 control logic for injection-control applications in manufacturing environments.
