PRODUCT INFORMATION
Product Overview
The ABB DI831 3BSE013212R1 is a 16-channel digital input module for S800 I/O systems. It operates at a nominal rating of 48 V d.c. using current sinking signal circuitry. The normal input voltage range spans 36 to 60 V d.c. during active operation. Each input channel draws a nominal current of 4 mA at 48 V d.c.
Each channel includes current limiting, EMC protection components, an optical isolation barrier, and an input state LED. The module cyclically executes internal self-diagnostics to verify process voltage and time synchronization. Digital input filter times can be adjusted from 0 to 100 ms to reject noise pulses. It supports Sequence of Events recording with a resolution of 0.4 ms.
