ABB DI840 3BSE020836R1 Digital Input Module

Designed for demanding industrial environments, the ABB DI840 3BSE020836R1 digital input module delivers precise signal acquisition in automation systems. With 16 isolated input channels and 220V AC/DC compatibility, it handles complex control tasks across manufacturing, energy management, and process industries. Engineers appreciate its ability to maintain accuracy under electrical interference and temperature fluctuations.

In production lines requiring precise sensor monitoring, this module maintains reliability where others fail. A steel plant maintenance manager recently mentioned how its galvanic isolation reduced false triggers in their rolling mill control system. We frequently pair it with ABB’s AC800M controllers and complement with similar modules like the DI810 (3BSE018102R1) and DI820 (3BSE018103R1). Clients in energy sectors also combine it with our inventory of GE VMIVME-7807 and Woodward 8521-0312 components for hybrid system builds.
