Product Introduction
The ABB DI825 3BSE036373R1 is a high-quality 16-channel digital input module developed for use in advanced industrial control systems. As part of ABB’s renowned S800 I/O series, this module plays a key role in the seamless acquisition of binary signals from field devices such as switches, push buttons, and proximity sensors. It is fully compatible with ABB’s AC 800M controllers and 800xA automation systems.
Designed to ensure robust performance and long-term reliability, the DI825 features electrical isolation on each channel, providing protection against interference and voltage spikes. It supports hot swapping, allowing users to replace the module without shutting down the system. With built-in LED indicators for each channel, the module enables fast fault diagnostics and system monitoring. The compact structure and DIN-rail mounting make it ideal for space-limited environments.
