Solving the Discontinued Hardware Crisis

DOLD's BN series safety relays and their associated extension modules were widely deployed across European and Asian manufacturing facilities throughout the 1990s and 2000s. These systems were engineered for 20–30 year operational lifespans, and many remain in active service today — embedded in press control systems, conveyor safety circuits, and machine guarding architectures that were never designed for modular replacement.

The BN3081 Extension Module serves a specific function within these platforms: expanding the output contact capacity of the base safety relay without requiring additional wiring infrastructure or controller reprogramming. When this module reaches end-of-life through component fatigue or electrical fault, there is no modern drop-in equivalent that preserves the existing wiring schema and safety certification chain.

Plant engineers facing this situation have three options: source an original BN3081, undertake a full safety system redesign, or accept operational risk by running degraded. The first option is the only one that preserves production continuity, maintains existing safety certifications, and avoids capital expenditure. DriveKNMS exists to make that first option available.

How to extend your automation asset life by 5–10 years through strategic spare parts management:

For factory management under pressure to justify continued operation of legacy systems rather than capital-intensive upgrades, the arithmetic is straightforward: a proactive spare parts strategy for obsolete components typically costs 2–5% of what a forced system modernization would require. The BN3081 is a concrete example of where that investment pays off.
