TheABB DI825is a high-performance 8-channel digital input module designed for the S800 I/O system. Its primary advantage isindividual galvanic isolationfor every single channel, making it ideal for monitoring signals from different power sources or phases within a single module. Whether you are dealing with diverse AC or DC field signals, the DI825 provides superior protection against ground loops and electrical interference in mission-critical automation environments.

Key Performance Features
Total Channel Independence:Every input channel is electrically separated from the others. This allows for simultaneous monitoring of AC and DC signals from disparate sources without risk of cross-channel faults.
High-Voltage Resilience:Built to handle up to 230 V AC or 125 V DC, making it highly suitable for power plant applications, substations, and heavy industrial motor control.
Built-in Filtering:Features digital filtering to eliminate signal chatter and contact bounce, ensuring the AC 800M controller receives clean, accurate data.
High-Density Safety:Despite its high-voltage capability, the module maintains a compact 45 mm width, optimizing cabinet rail space.
