The DI810 (3BSE008508R1) serves as a high-performance 16-channel digital input interface within the ABB S800 I/O system. Engineered for 24 V DC logic environments, this module enables seamless integration of field sensors, switches, and pushbuttons into Advant Controllers or other compatible process stations.
The module features a compact S800 form factor with integrated signal conditioning and group-wise galvanic isolation, ensuring reliable signal acquisition in electrically noisy industrial environments. Each channel includes current-limiting circuitry for protection against short circuits and transient disturbances.
| Specification | Description |
|---|---|
| Module Identity | DI810 (3BSE008508R1) |
| Input Channels | 16 single-ended channels |
| Rated Voltage | 24 V DC (EN 61131-2 Type 1 compliant) |
| Input Logic | Current sinking (Active High) |
| Isolation | Group-wise galvanic isolation via optocouplers (50 V continuous) |
| Power Consumption | Max. 50 mA from 24 V source |
| Process Signal Delay | Configurable hardware filters (typically 1 ms to 15 ms) |
| Mechanical Dimensions | 124 mm × 45 mm × 102 mm (S800 standard profile) |
| Weight | 0.15 kg |
The DI810 is typically deployed in discrete control and monitoring applications, including:
Conveyor and material handling system feedback
Motor starter and contactor status monitoring
Safety interlocking logic
General-purpose digital signal acquisition in pulp & paper, power generation, and chemical processing facilities
Its compliance with EN 61131-2 Type 1 input characteristics makes it suitable for standard 24 V DC industrial sensor networks.
Why is the Fault LED illuminated?
This typically indicates either:
Missing or unstable 24 V DC external supply
Internal hardware fault detected during self-diagnostics
Improper connection at the MTU (Module Termination Unit)
Verify supply voltage and MTU wiring before replacing the module.
Can the DI810 be hot-swapped?
Yes. The S800 I/O architecture supports Hot Configuration in Run (HCIR), allowing module replacement without shutting down the entire I/O station, provided the baseplate remains powered and system configuration permits.
