WOODHEAD SST-DN3-PCU-1 DeviceNet Interface Card | SST DeviceNet Platform
Engineering Background
The WOODHEAD SST-DN3-PCU-1 is a high-performance DeviceNet interface card engineered for seamless integration between host PCs and DeviceNet industrial networks. Developed under the SST (Spectrum System Technology) platform — now part of the Molex/Woodhead industrial connectivity portfolio — this card has established a proven track record in demanding factory automation environments where deterministic communication and robust I/O management are non-negotiable.
Product Positioning
Designed for system integrators, OEM machine builders, and plant automation engineers who require a reliable, standards-compliant DeviceNet master/slave interface. The SST-DN3-PCU-1 bridges the gap between Windows-based SCADA/HMI platforms and the DeviceNet field bus layer, enabling real-time device monitoring, configuration, and control without proprietary hardware lock-in.

System Architecture & Signal Flow
The SST-DN3-PCU-1 installs into a standard PCI slot on the host PC motherboard. The on-board DeviceNet controller (CAN ASIC) manages all network timing, arbitration, and message queuing autonomously, offloading the host CPU. The SST API provides a memory-mapped I/O interface: the application writes output data to a shared dual-port RAM region; the card’s firmware executes the DeviceNet scan cycle and updates input data tables in real time. Optical isolation on the DeviceNet port decouples the PC ground reference from the field bus, ensuring signal integrity across long cable runs (up to 500 m at 125 kbps).
Signal Flow: Host Application → SST API DLL → PCI Bus → On-board CAN Controller → Optical Isolator → DeviceNet Network → Field Devices (I/O, Drives, Sensors)

Technical FAQ
Q: Is the SST-DN3-PCU-1 compatible with Windows 10 64-bit?
A: Yes. SST provides a 64-bit driver package for Windows 10. Confirm the driver version (≥ v4.x) matches your OS build before installation.
Q: Can this card operate as both Master and Slave simultaneously?
A: No. The card operates in one mode at a time, selectable via the SST API initialization call. Mode switching requires a re-initialization of the network stack.
Q: What is the maximum cable length supported?
A: 500 m at 125 kbps; 250 m at 250 kbps; 100 m at 500 kbps — per DeviceNet specification IEC 62026-3.
Q: Does Konmask provide the SST software/driver CD?
A: Driver packages are available for download from the Molex/SST support portal. Konmask can provide the download link and installation guidance upon request.
Q: What is the lead time for this part?
A: Typically 3–7 business days for in-stock units. Contact us for urgent requirements.
Q: Is a new or refurbished unit available?
A: Konmask offers both new (factory-sealed) and tested-surplus units. Condition is clearly stated on the quotation.
