Description

The Woodward SST-DN3-PCU-2-E is a high-performance, dual-channel DeviceNet communication interface card designed for seamless integration between industrial PCs and field-level devices. Utilizing a universal PCI bus architecture, this module provides reliable, deterministic communication for complex automation environments. By offloading protocol processing from the host computer to its onboard processor, the card ensures rapid data throughput and minimizes system-level bottlenecks, making it an ideal solution for high-density I/O control applications.

Features

• Dual-channel architecture for managing two independent DeviceNet networks simultaneously.
• Universal PCI bus compatibility (supports both 3.3 V and 5 V signaling).
• Configurable as a Master/Scanner or Slave on either channel.
• Supports standard DeviceNet baud rates: 125, 250, and 500 kbps.
• Integrated isolation circuitry to protect the host PC from network-side electrical surges.
• Enhanced firmware support for integration with OPC servers and custom DLL-based software environments.

Applications

This interface card is widely utilized in industrial automation, material handling systems, and food processing plants where robust, high-speed fieldbus communication is required. Its dual-channel capability allows for network segmentation or redundant communication paths, improving overall system availability and maintenance efficiency.

Installation Guidelines

• Ensure the host computer is powered down and disconnected from the AC power source before installing or removing the PCI card.
• Handle the card by its edges; avoid touching the gold-plated edge connector pins to prevent oxidation or contamination.
• Ensure the card is firmly seated in a compatible PCI slot and secured with the mounting screw to prevent vibration-induced disconnection.
• Use shielded twisted-pair cabling for DeviceNet connections to minimize EMI interference.
• Ensure proper grounding of the DeviceNet network shield at the designated point to maintain signal integrity.
• Verify that the host PC BIOS/OS recognizes the card before initializing communication software.

FAQ

Is the SST-DN3-PCU-2-E compatible with both 3.3V and 5V PCI slots?

Yes, the card features a universal PCI bus architecture that supports both 3.3 V and 5 V signaling environments.

Can this card operate as a Master and a Slave simultaneously?

Yes, the dual-channel configuration allows for independent channel operation, meaning you can configure one channel as a Master/Scanner and the other as a Slave, or both as Masters/Slaves depending on your network requirements.
