Triple Modular Redundancy (TMR) and Fail-Safe Execution
The module processes incoming pulse transitions across three independent channels to execute triple modular redundancy (TMR) algorithms. Channel-to-channel galvanic isolation rating at >=500 VDC suppresses field signal cross-talk and blocks high-voltage noise spikes from penetrating the central system bus. Integrated internal diagnostic routines continuously execute precision reference tests, isolating channel discrepancies and forcing a fail-safe state execution without interrupting active turbine overspeed or machinery protection functions.
Frequently Asked Questions
Q: Can the P13381 pulse input module be replaced online without powering down the Tricon rack?
A: Yes, online hot-replacement is supported. The module can be extracted and inserted into a live chassis slot without interrupting active logic execution or tripping safety protection loops.
Q: How does the module handle signal conditioning for passive magnetic pick-ups versus active sensors?
A: The module accommodates differential or single-ended signal configurations across its 6 input channels, processing both non-amplified magnetic pick-ups and active open-collector inputs within a +/-33 VDC maximum threshold.
Field Installation Guidelines
Observe strict electrostatic discharge precautions when handling the module. Slide the card into the designated Tricon baseplate slot until the rear connectors lock firmly into the backplane, and tighten all retaining screws to establish frame grounding. Run field sensor wiring through shielded twisted-pair cables, routing signal conduits away from high-voltage AC lines. Terminate cable shields directly at the system earth ground bar to maintain signal integrity and prevent electromagnetic interference.
