ABB DI831 (3BSE013212R1) Digital Input Module
Product Description
The ABB DI831 (3BSE013212R1) is a high-density digital input module engineered for the AC500 automation platform. Offering 32 isolated input channels in a single compact housing, it enables extensive signal collection without expanding cabinet real estate. Constructed for industrial robustness, the module features optical isolation per channel, rapid response times, and immunity to electrical noise. With dimensions of 45 × 102 × 119 mm and a weight of 0.22 kg, the DI831 mounts easily on DIN rails, integrating seamlessly into ABB’s modular I/O backplane.
