3BSE036373R1 | ABB DI825 Digital Input Module

Overview

The DI825 (Article Number: 3BSE036373R1) is an 8-channel digital input module designed for the S800 I/O system. It supports 125 V d.c. inputs, offering individually isolated channels. This module is equipped with current-limiting components, EMC protection, input state indication LEDs, and optical isolation barriers. Channels 1 and 8 can be used for voltage supervision, ensuring reliable field input power by monitoring voltages on channels 2-4 and 5-7.

Key Features & Benefits

8 Channels for 125 V d.c. inputs
Individually isolated channels to ensure safety and reliability
Voltage supervision for field input power via Channels 1 and 8
Input status indicators for each channel
Sequence of Event (SOE) functionality for precise event recording
Signal filtering options for reducing noise (0-100 ms)
