SST PB3-PCI-e / PB3-PCU PROFIBUS Interface PCI Card – SST PROFIBUS Series
When a PROFIBUS master or slave interface fails on the factory floor, the consequences are immediate and severe: entire production lines halt, PLCs lose communication with field devices, and engineers scramble to diagnose a silent network. In process industries, pharmaceutical manufacturing, and automotive assembly, even minutes of unplanned downtime translate into tens of thousands of dollars in losses. The SST PB3-PCI-e / PB3-PCU PROFIBUS Interface PCI Card is the critical link that keeps your PROFIBUS DP network alive — a component you simply cannot afford to be without.
Within the SST PROFIBUS Series, the PB3-PCI-e and PB3-PCU represent SST’s proven PC-based PROFIBUS connectivity solution. SST (Woodhead / Molex SST) has been a globally recognized name in fieldbus interface technology for over two decades, with installations across thousands of industrial facilities worldwide. The PB3-PCI-e targets modern PCIe-slot host systems, while the PB3-PCU serves legacy PCI-slot environments — together covering the broadest range of industrial PC platforms in use today.

Frequently Asked Questions
- Q: What is the difference between the PB3-PCI-e and PB3-PCU?
- A: The PB3-PCI-e uses a PCI Express slot (suitable for modern industrial PCs), while the PB3-PCU uses a standard PCI slot (for legacy systems). Both provide identical PROFIBUS DP functionality.
- Q: Can this card operate as both master and slave simultaneously?
- A: The card is configurable as master or slave. Please refer to the SST configuration software documentation for multi-mode operation details specific to your firmware version.
- Q: Is this card compatible with Siemens STEP 7 or TIA Portal?
- A: The SST PB3 series uses SST’s own driver and configuration suite. Integration with Siemens engineering tools is possible via OPC or third-party middleware — contact us for application-specific guidance.
- Q: What operating systems are supported?
- A: Windows-based operating systems are supported. Please confirm your OS version with our team to ensure driver compatibility.
