Butler DC29511-501 Printed Circuit Board

DC29511-501 Printed Circuit Board by Butler Automatic is a plug-in PLC/add-on board designed for use within Butler automation systems. Catalog listings describe it simply as a PC Board that functions as an expansion or interface module within a larger PLC or machine-control configuration, with the DC29511-501 model number tying it to Butler's backplanes or I/O expansion ecosystems. In dealer inventories, the part is categorized under PLCs/Machine Control, confirming its role as a component rather than a standalone controller. Verified listings across distributors identify the same DC29511-501 part in Butler Automatic product lines, and some sources note that this model has been discontinued by the manufacturer, which can affect availability and compatibility with older installations. This board is intended to be installed as part of an existing Butler automation setup to provide additional connectivity or function within a compatible chassis, rather than serving as a complete, independent device.
