Power Plant DCS Solution — WESTINGHOUSE 7379A06G02 | Low Power I/O Expansion Board
Where This Product Is Used
The WESTINGHOUSE 7379A06G02 (alternate P/N: 3A99160G02) Low Power I/O Expansion Board is a critical field I/O interface module deployed across a wide range of industrial and utility environments:
- Nuclear & Fossil Fuel Power Plants — Integrated into Westinghouse WDPF and Ovation DCS architectures for turbine control, feedwater regulation, and balance-of-plant monitoring.
- Combined Cycle & Gas Turbine Plants — Used in distributed I/O racks to interface analog and digital field signals with the main control processor.
- Petrochemical & Refinery Process Control — Deployed in safety-instrumented and regulatory control loops requiring low-power, high-reliability I/O expansion.
- Water Treatment & Utility Infrastructure — Supports SCADA-integrated DCS panels where compact, low-power I/O boards reduce panel heat load.
- Pulp, Paper & Heavy Industry — Extends I/O capacity in existing Westinghouse control cabinets without requiring full rack replacement.

Why Engineers Specify This Model
- Low Power Architecture — Minimizes thermal load within densely populated I/O racks, extending MTBF and reducing cooling requirements in sealed enclosures.
- Dual Part Number Compatibility — Cross-referenced as both 7379A06G02 and 3A99160G02, ensuring seamless drop-in replacement across different revision levels of Westinghouse DCS documentation.
- Proven Field Reliability — Designed to Westinghouse’s stringent utility-grade standards, this board has accumulated decades of runtime in continuous-process environments.
- Backward Compatible — Integrates with existing WDPF backplane and Ovation I/O rack infrastructure without firmware or hardware modification.
- Reduced Downtime Risk — Having a verified spare on-hand eliminates extended outages caused by long OEM lead times for legacy DCS components.

Compliance & Industry Standards
- IEEE 603 / IEEE 7-4.3.2 — Designed in alignment with nuclear safety system criteria applicable to Westinghouse utility installations.
- IEC 61511 / IEC 61508 — Compatible with SIL-rated process safety architectures when integrated per site-specific safety analysis.
- RoHS Compliance — Refurbished units processed and tested in accordance with applicable environmental directives.
- CE Marking — Available on select units; documentation provided upon request.
- ISO 9001 Sourcing — All units sourced and inspected under quality management procedures aligned with ISO 9001 principles.
Quality Assurance & Sourcing
At Konmask.com, every Westinghouse legacy module undergoes a structured quality process before shipment:
- Visual Inspection — PCB examined for corrosion, burnt components, cracked solder joints, and physical damage.
- Functional Bench Test — Board powered and tested against known-good reference signals to verify I/O channel integrity.
- Cleaning & Reconditioning — Ultrasonic or IPA cleaning applied where applicable; conformal coating inspected.
- Traceability Documentation — Each unit ships with inspection record, test report, and sourcing declaration.
- Secure Packaging — ESD-safe anti-static bags, foam-lined cartons, and moisture barrier packaging for international transit.
We source exclusively from decommissioned plant inventories, authorized distributors, and verified industrial surplus channels — never from unverified grey-market brokers.
How to Source This Part
- Confirm Part Number — Verify your system documentation references 7379A06G02 or 3A99160G02 (both are the same board, different revision labels).
- Request a Quote — Email [email protected] with your required quantity, condition preference (new / refurbished / tested), and delivery timeline.
- Review Test Report — We provide a pre-shipment test report for all refurbished units. New-in-box units include OEM documentation where available.
- Place Order & Confirm Shipping — We ship via DHL Express, FedEx International, or freight forwarder per your preference. Export documentation (commercial invoice, packing list, COO) included.
- Receive & Install — Units arrive in ESD-safe packaging. Installation should follow Westinghouse WDPF/Ovation system integration procedures.
Application-Specific FAQ
Q: Is 7379A06G02 the same as 3A99160G02?
A: Yes. These are dual part numbers for the same Low Power I/O Expansion Board — 7379A06G02 is the assembly drawing number and 3A99160G02 is the catalog/ordering number used in different Westinghouse documentation revisions.
Q: Which Westinghouse DCS platforms is this board compatible with?
A: This board is designed for the Westinghouse WDPF (Westinghouse Distributed Processing Family) and is also referenced in early Ovation system documentation. Confirm compatibility with your specific rack revision before installation.
Q: Can this board be used in a safety-critical (SIL) application?
A: Only when integrated per a site-specific safety analysis and validated by your plant’s I&C engineering team. Konmask supplies the hardware; SIL validation is the responsibility of the end-user’s engineering authority.
Q: Do you offer warranty on refurbished units?
A: Yes. All tested and refurbished units carry a 12-month functional warranty covering defects identified under normal operating conditions. See our warranty policy at konmask.com for full terms.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, sourcing typically takes 2–4 weeks. Contact us for real-time availability.
Q: Can you supply multiple units for a plant-wide spare parts program?
A: Yes. We support bulk procurement for planned maintenance outages and spare parts inventory programs. Volume pricing available — contact [email protected].
