Description
The Woodhead Molex SST-PFB3-VME-2-E is a high-performance communication interface card designed for VME bus systems, enabling direct data exchange between a VME-based industrial chassis and a Profibus DP field network. Automation engineers deploy this card into heavy-industry control racks to act as a Profibus DP Master or Slave, handling complex protocol management directly on the board to offload processing cycles from the host VME controller. Are you upgrading an older VME chassis configuration? The startup procedure for the newer SST-PFB3-VME architecture requires an explicit AutoRun command set via serial terminal to load firmware on boot—a significant change from legacy 5136-PFB-VME cards that catches many field teams off guard.

Commercial Condition and Global Logistics Availability
We supply the SST-PFB3-VME-2-E in New Surplus or Refurbished (Tested) conditions. Given that the manufacturer has discontinued this specific line of VME modules, our technicians verify every circuit track and port driver on an active VME test chassis under a continuous 12 Mbps communication load before signing off on export clearance.
- Availability: Stocked in regional fulfillment centers for immediate deployment
- Lead Time: Dispatches within 1 to 2 business days from order verification
- Warranty: 12-month comprehensive warranty covering physical component integrity
- Pricing Note: The listed price functions as a standard commercial index. Final market pricing fluctuates based on vintage component scarcity and remaining warehouse lot sizes. Contact our logistics desk to request an official quotation.
Cross-Border Logistics and Export Control Compliance
Exporting specialized legacy processing cards like the SST-PFB3-VME-2-E involves precise regulatory tracking. We schedule urgent international air freight through DHL Express, FedEx, and UPS to minimize downtime across primary industrial hubs in North America, Europe, Australia, and Asia-Pacific.
This hardware carries the global HS Code 8517.62.00 (or regional variant 8542.31.90 depending on local customs definitions for integrated communication subassemblies). Because these modules integrate flash memory and protocol processing stacks often used in older critical infrastructure systems, our compliance team prepares comprehensive commercial invoices indicating the exact manufacturer part number and serial codes. This prevents border agents from mistaking the legacy communication card for modern restricted encryption hardware, avoiding customs delays at your destination port.
Woodhead SST VME Frequently Asked Questions
- Can I access the card’s diagnostic serial port while the host VME controller is running?Well, technically you can only establish a clean serial terminal connection to the SST-PFB3-VME-2-E right at startup while the initial boot code executes. In our field experience, trying to hook up via HyperTerminal after the main
pfb3.ss3firmware image takes control of the board will result in a locked terminal screen or corrupted ASCII text feedback. - Does this card support process-consistent data across the dual-port RAM?Yes, the onboard memory map utilizes a hardware-enforced semaphore locking mechanism at the device level. This ensures that the host VME system never reads a partially overwritten network packet during a high-speed 12 Mbps Profibus DP cyclic update.
