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
