Low Voltage Digital Input Module ABB DI01
Description
ABB DI01 Low Voltage Digital Input Module is an industrial-grade discrete input module belonging to ABB’s compact I/O module series. It is designed to collect discrete field signals such as sensor on/off signals, button switch signals, and limit switch signals, then transmit them stably to ABB PLCs (like AC500 series, AC800M series) or distributed control systems (DCS) to provide accurate field signal support for industrial automation control.
