Features:
- SOE recording: ABB documents 1 ms event resolution and a 257-event queue.
- Single or redundant use: The module supports both approved configurations.
- Supervised sensor power: Current-limited transducer power and diagnostics support field monitoring.
This model is the SOE-capable, redundant-ready 24 V digital input configuration and differs materially from DI810.
It time-stamps field transitions, supervises sensor power, and reports detailed module and channel diagnostics to the control system.
Confirm controller time synchronization, event collection, redundancy layout, sensor-power loads, MTU orientation, and channel mapping before commissioning.
Availability is subject to Apter Power inventory and sourcing confirmation.

Event-recording preparation
- Time source: Confirm controller and I/O time synchronization.
- Event resolution: Use the ABB-documented 1 ms event handling in the design.
- Queue handling: Review how the host collects and clears recorded events.
- Shutter filter: Configure filtering only from the approved cause-and-effect design.
Redundant input checks
- Architecture: Confirm single or redundant operation in the hardware design.
- MTU selection: Match the termination unit and mounting orientation.
- Channel pairing: Keep redundant signal paths and tags documented.
- Transfer test: Validate the approved changeover and diagnostic behavior.
Transducer-supply review
- Distribution: Map the current-limited outputs to the intended channels.
- Load: Keep each sensor-power circuit within ABB limits.
- Supervision: Test process-power alarms before service.
- Fault isolation: Separate field-device, power, wiring, and module causes.
