Technical Dossier
The Fuji Electric NB-series PLC module set — comprising the WPLAC-00, WPLAC-30, and JBLKC-00 — represents a category of industrial automation components with a narrowing availability window. As Fuji Electric progressively migrates its PLC ecosystem toward newer platforms, procurement teams relying on legacy NB-series infrastructure face a compounding challenge: sourcing authentic spare parts before secondary market supply dries up entirely.
For procurement managers in steel, petrochemical, automotive assembly, and discrete manufacturing, the cost of a single unplanned PLC-related downtime event routinely exceeds the annual spare parts budget for an entire production line. This page is designed to give you the data you need to make a defensible sourcing decision — not a sales pitch.

Procurement decisions for legacy PLC modules are rarely about unit price alone. The true cost calculation must account for Total Cost of Ownership (TCO) across three dimensions:
1. Spare Parts Turnover Rate: NB-series modules have a relatively low turnover rate in the secondary market, meaning that holding one or two units as critical spares is a defensible inventory strategy. The risk of over-stocking is low; the risk of under-stocking — and facing a 6–12 week lead time during a production emergency — is high.
2. Downtime Cost vs. Part Cost: For a mid-scale manufacturing facility, one hour of unplanned downtime typically costs USD $5,000–$50,000 depending on the production value of the line. A pre-positioned spare module at a fraction of that cost is not an expense — it is risk mitigation capital.
3. Sourcing from DriveKNMS vs. OEM Direct: Fuji Electric's official distribution channels may no longer carry NB-series modules as active stock. Authorized distributors often quote 8–16 week lead times for legacy parts, if available at all. DriveKNMS maintains a global sourcing network specifically for industrial automation spares, enabling faster fulfillment at competitive pricing — without compromising on authenticity or documentation.
Global Sourcing Network: We maintain relationships with authorized distributors, OEM surplus channels, and vetted secondary market suppliers across Japan, Europe, and North America. When a part is scarce, we know where to look — and more importantly, where not to look.
Part Number Verification & Cross-Reference: Our technical team cross-references part numbers against OEM documentation to prevent costly mis-procurement. If WPLAC-00 has a compatible successor or a cross-brand equivalent, we will tell you — even if it means a lower-margin sale for us.
Financial & Trade Compliance: All transactions are conducted with full export compliance documentation. We support buyers in regulated industries (defense-adjacent manufacturing, nuclear, aerospace) with the paperwork trail required for internal audit and procurement governance.
Repeat Order Management: Enterprise clients can establish blanket purchase orders with scheduled releases, reducing administrative overhead and locking in pricing against market volatility.
Q: What payment terms are available?
A: Standard terms are 100% T/T in advance for first-time orders. Established clients may qualify for net-30 or LC arrangements. Contact us to discuss your requirements.
Q: What is your warranty policy?
A: 12 months from shipment date. If a unit fails under normal operating conditions within the warranty period, we will replace it or issue a full refund. We do not cover damage from incorrect installation, overvoltage, or environmental factors outside the OEM specification.
Q: Do you offer volume discounts?
A: Yes. Pricing is tiered based on quantity. Submit an RFQ with your required quantity and delivery schedule for a formal quotation.
Q: What is your return policy?
A: Returns are accepted within 30 days of receipt for unused, unopened units in original packaging. RMA authorization is required prior to return shipment. Return freight is the buyer's responsibility unless the return is due to our error.
Q: Can you source this part if it is not currently in stock?
A: Yes. Submit an RFQ and our sourcing team will provide a lead time estimate within 24–48 business hours. We will not confirm an order we cannot fulfill.
