Features:
- 48 V DC input service: Sixteen current-sinking channels use the ABB-documented thresholds.
- Two supervised groups: Each group of eight has separate process-voltage monitoring.
- Selectable filtering: Four digital filter times are available for contact behavior.
This model is defined by its 48 V DC input service and must not be confused with the 24 V DI810 configuration.
It reports field states and group supply status through the S800 ModuleBus while providing front channel indication.
Confirm the field voltage, thresholds, input-group wiring, supervision inputs, filter time, MTU, and keying before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

Field-voltage preparation
- Supply class: Verify the approved 48 V DC field source.
- Thresholds: Check the field device states against ABB on/off ranges.
- Polarity: Confirm current-sinking wiring before energizing.
- Isolation groups: Keep the two eight-channel groups correctly separated.
Contact-response checks
- 2 ms: Use only when the approved signal requires the fastest listed filter.
- 4 or 8 ms: Match the engineering database and contact behavior.
- 16 ms: Use the longer listed filter only with the approved timing.
- Validation: Test real transitions and alarms after configuration.
48 V input troubleshooting
- No recognition: Measure field voltage and compare it with the documented thresholds.
- Group warning: Check the matching process-voltage supervision input.
- Chatter: Review filter time, contact quality, shielding, and grounding.
- Wrong logic: Verify sinking signal polarity and channel mapping.
