Sumitomo Heavy Industries, Ltd. JA760879AC Circuit Board

Sumitomo Heavy Industries JA760879AC is a MS-D series circuit board used as a controller module within Sumitomo machinery. This printed circuit board (PCB) functions as part of the MS-D control architecture and includes LED status indicators to aid on-site diagnostics and monitoring of the board’s operating state. The JA760879AC/MS-D designation is how the part is listed by Sumitomo Heavy Industries and is found in product listings from distributors such as PLC Machinery and Radwell Replacements. According to Radwell, the JA760879AC MS-D controller board has been discontinued by the manufacturer, which can impact future availability and support options; buyers commonly source remaining stock or refurbished units through authorized resellers. In industrial automation contexts, this board would typically serve as a control-component within legacy Sumitomo MS-D installations, interfacing with other controller modules and I/O subsystems to coordinate sensors and actuators in heavy machinery environments. Multiple distributors, including PLC Machinery, Radwell, and York Controls, catalog the JA760879AC MS-D circuit board, including refurbished units.
