ABB DI880 3BSE028586R1 – 16-Channel Digital Input Module (S800 I/O Series)
Product Introduction
The ABB DI880 (3BSE028586R1) is a high-density digital input module designed for the S800 I/O family, commonly used in ABB AC 800M, 800xA, Freelance, and Advant control systems. It provides 16 galvanically isolated 24 V DC digital inputs, making it suitable for industrial process applications requiring reliable monitoring of field devices such as switches, sensors, and pushbuttons.
This module supports ModuleBus communication, diagnostic reporting, hot-swapping, and built-in noise filtering, ensuring long-term stability in harsh environments.

Power generation (gas, steam, hydro turbine control signals)
Oil & gas upstream/downstream I/O cabinets
Water & wastewater plants (pump status, limit switches, alarms)
Factory automation and safety interlock monitoring
Marine and offshore control panels
Installation & Commissioning Notes
Install onto TU base before connecting field wiring
Ensure input common (0 V reference) is shared across sensors
Recommended to enable debounce filtering for mechanical switches
Signal test can be performed via system diagnostics in 800xA / Control Builder
Use shielded cable in high-EMI environments
Module automatically detected by the controller upon power-up
Maintenance & Lifecycle
No calibration required
Replaceable while powered; system auto-recognizes replacement
Input status can be read via system diagnostics for troubleshooting
Suggested spares: 1 DI880 per cabinet or per 10 modules installed
Fully supported in 800xA v6 and v7 LTS product lifecycle
Additional Information
Ordering code 3BSE028586R1 = Standard industrial temperature range, RoHS compliance
Successor module to older DI810 and DI801 where higher density is required
Compatible with SIL-rated safety system when used with certified logic controllers
