Features:
- Provides 32 commoned inputs for nominal 24 V DC signals.
- Uses triplicated signal paths for Trident safety processing.
- Scans all input points in less than 1 ms with field voltage diagnostics.
The current ordering identity is DI3301, corresponding to the Trident model 3301 32-point digital input module.
It converts commoned 24 V DC field states into triplicated input data for the safety application.
Match the baseplate, termination, common wiring, system revision, channel map, and proof-test method before installation.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Acquire discrete trip, permissive, alarm, and equipment-status signals in a Trident application.
- Monitor nominal 24 V DC field contacts through the documented on and off thresholds.
- Replace a verified model 3301 module during controlled safety-system maintenance.
- Forced-value diagnostics test input paths with a disturbance shorter than 2 ms per test.
- The documented diagnostic glitch remains below 2 ms and approximately 36 percent of test voltage.
- Input-path diagnostics operate within the maximum specified toggle-rate condition.
- All 32 input points are scanned in less than 1 ms.
- Signals from 0 to 5 V DC are interpreted off and 15 to 30 V DC are interpreted on.
- The 6 to 14 V DC transition region must not be treated as a valid steady field state.
- Functional-to-protective-earth isolation is documented at 500 V DC minimum.
- Functional-to-functional-earth isolation is documented at 800 V DC minimum.
- The module must be installed and proof-tested within the certified Trident system configuration.
