51304690100

51304690100 (51304690-100) is a high‑precision Digital Input Module with SOE (Sequence of Events) capability, designed for Honeywell TDC3000 / UCN DCS systems. It captures millisecond‑level state changes of field contacts (switches, relays, safety interlocks) for accurate event sequencing and root‑cause analysis after process trips.

Description

1. Product Overview

51304690100 (51304690-100) is a high‑precision Digital Input Module with SOE (Sequence of Events) capability, designed for Honeywell TDC3000 / UCN DCS systems. It captures millisecond‑level state changes of field contacts (switches, relays, safety interlocks) for accurate event sequencing and root‑cause analysis after process trips.

2. Part Number & Physical Details

  • Part Number: 51304690100 (51304690‑100)

  • Module Type: Digital Input SOE Card (TDC3000/UCN)

  • Dimensions: 318 × 29 × 278 mm

  • Weight: Approx. 0.59–1.0 kg

  • Mounting: Standard UCN/APM rack slot

3. Technical Specifications

  • Input Voltage: 24 VDC (field‑side)

  • Input Channels: 16 isolated digital inputs

  • SOE Resolution: 1 ms (high‑resolution timestamping)

  • Filtering: Each channel has noise filtering to prevent false triggering

  • Isolation: Channel‑to‑backplane isolation

  • Coating: Conformal coated PCB for harsh environments

4. Key Features

  1. SOE Sequence Recording: Captures precise 1 ms timestamps for all input transitions.

  2. High Noise Immunity: Per‑channel filtering rejects electrical interference.

  3. 16 Isolated Inputs: Monitors discrete devices (switches, interlocks, relays).

  4. Industrial Hardening: Conformal coating protects against dust, moisture, and contaminants.

  5. LED Status Indicators:

    • PWR (Green): Steady = power OK

    • RUN (Green): Flashing = module active

    • FLT (Red): On = input fault or diagnostic error

  6. Hot‑Swappable: Online replacement without system shutdown.

5. Application Range

  • Target Systems: Honeywell TDC3000, UCN DCS

  • Industries: Power, chemical, oil & gas, refining, water treatment.

  • Function: SOE event logging, critical contact monitoring, trip analysis.

6. Installation Instructions

  1. Power off the rack before insertion/removal.

  2. Insert into standard UCN slot and secure.

  3. Use twisted‑pair shielded cable for field inputs.

  4. Route cables away from high‑voltage lines.

  5. Ground shields at one end only to avoid loops.

7. Maintenance Notes

  • Inspect connections quarterly; clean with dry cloth only.

  • Avoid harsh solvents; use only genuine Honeywell spares.

  • If FLT LED is on, check field wiring and input voltage.

8. Safety Requirements

  • All wiring/maintenance must be done with power off.

  • Do not exceed rated voltage/temperature.

  • Do not disassemble the module.
