Industrial PLC and DCS control boards with military-spec gold plating on all connectors and high-reliability components. The Siemens PLC CPU Module Board v5 contains approximately 2150mg of gold per pound, 70mg of palladium per pound, and 14% copper by weight. At current August 2026 market rates, this translates to approximately $3.52 per pound in scrap value.
Siemens is known for high-quality manufacturing standards, which often means higher precious metal content in their PCBs compared to generic alternatives. The gold plating on edge connectors, CPU socket pins, and high-speed signal traces is thicker and purer than consumer-grade boards, making them more valuable per pound at the refinery.
At ScrapMetalBuyers.com, we buy scrap circuit boards in bulk from data center decommissions, electronics recyclers, and ITAD companies. We focus on commercial-scale lots of 50 lbs or more. Sean handles every deal personally — no brokers, no middlemen, same-day payment.

Understanding where these boards come from and how they were used is critical to accurately assessing their scrap value — boards from certain industries carry heavier gold plating, more complex BGA packages, and higher-value precious metal profiles than visually similar boards from other sectors.
Siemens S7 series CPU modules use custom ASICs developed by Siemens for real-time deterministic control. The S7-400H redundant CPUs feature synchronization modules with fiber optic links. All S7 CPU boards use gold-plated backplane connectors (DIN 41612 format) with 64 or 96 pin configurations. The PROFIBUS and PROFINET communication interfaces use gold-plated D-sub and RJ45 connectors respectively.
The fifth production revision often coincides with a transition to newer component generations while maintaining backward compatibility. Fifth-revision boards may incorporate newer BGA package styles with different gold content profiles compared to earlier revisions. These boards are typically 4–11 years old at current market conditions.
Migration from S5 to S7 platforms, S7-300 to S7-1500 upgrades, and factory automation modernization projects generate the largest volumes. German automotive manufacturers (VW, BMW, Mercedes) and their global supply chains are major sources of Siemens PLC scrap.
Siemens PLC CPU modules from automotive and chemical applications are typically clean and well-maintained. Battery-backed SRAM modules may have depleted batteries — this does not affect scrap value. Conformal-coated boards from harsh environments are acceptable.
We buy single boards and bulk lots. Free pickup for 50+ lbs. Same-day payment on approved lots.
