3BSE008512R1 | ABB DI820 Digital Input Module

Overview

The DI820 (Article Number: 3BSE008512R1) is an 8-channel digital input module designed for the S800 I/O system. It is capable of handling 120 V a.c. and 110 V d.c. inputs. The module features individual isolation for each channel, ensuring safe and reliable signal processing. With built-in EMC protection, current limiting components, input state indication LEDs, and an analog filter, the DI820 offers precise control and supervision for your field inputs.

Key Features & Benefits

8 Channels for 120 V a.c. / 110 V d.c. inputs
Individually isolated channels for enhanced safety
Voltage supervision for field input power on channels 1 and 8
Input status indicators for real-time monitoring
Selectable signal filtering (2, 4, 8, 16 ms)
Current limiting for sensor power, controlled by the MTU
LED indicators for Fault (F), Run (R), Warning (W), and channel status
Error indication and supervision when voltage disappears on channels 1 or 8
