The Woodward SST-DN3-PCI-2 is a high-performance PCI-based DeviceNet interface card designed to provide reliable, deterministic connectivity between industrial PCs and DeviceNet fieldbus networks. By offloading the protocol stack processing from the host CPU, this module ensures efficient, real-time data acquisition and control, making it a critical component for power generation, oil and gas, and complex automation systems.
Features
Dedicated Onboard Processing: Manages the DeviceNet protocol stack to reduce host CPU load and ensure deterministic communication.
Flexible Configuration: Supports Master/Slave, Peer-to-Peer, and Multi-Master network configurations.
Advanced Messaging: Compatible with Polled, Cyclic, and Change-of-State (COS) messaging modes for optimized bandwidth.
Robust Isolation: Features optical isolation to protect the PCI backplane from electrical noise and field-side transients.
Industrial Reliability: Engineered for stability in high-vibration environments with high electromagnetic compatibility (EMC).
Applications
This communication card is typically utilized in industrial control environments requiring high-speed, reliable fieldbus integration. Common applications include turbine control systems, power plant monitoring, oil and gas process automation, and high-speed manufacturing lines where deterministic I/O updates are required.

Installation Guidelines
ESD Protection: Always handle the card by its edges and use a grounded wrist strap to prevent electrostatic discharge damage to internal components.
Power Down: Ensure the host industrial PC is completely powered down and disconnected from the AC source before inserting or removing the PCI card.
Seating: Ensure the card is firmly seated in a compatible PCI slot and secured with the mounting screw to maintain proper grounding and vibration resistance.
Cable Routing: Route DeviceNet network cables away from high-voltage power lines and sources of significant electromagnetic interference (EMI) to maintain signal integrity.
Cooling: Ensure the host PC chassis has adequate airflow to maintain the operating temperature within the specified 0 to 60 deg C range.
