Woodward SST-DN4-104-2 DeviceNet Interface Card

Description

The SST-DN4-104-2 is a high-performance DeviceNet interface card engineered for universal PCI bus architectures (3.3 V / 5 V). This module provides dual-channel connectivity, enabling industrial computers to act as a Master, Slave, or Peer-to-Peer node on DeviceNet networks. Designed as a direct replacement for legacy SST-DN3 series cards, it utilizes dedicated onboard processing to manage protocol tasks, effectively offloading the host CPU and ensuring deterministic communication performance in demanding industrial automation environments.

Features

• Dual-channel DeviceNet connectivity for high-density network management.
• Universal PCI bus compatibility (3.3 V and 5 V).
• Integrated onboard processor for reduced host CPU load and deterministic timing.
• Galvanic isolation (500 VDC) to protect the host system from electrical noise and transients.
• Supports all standard DeviceNet baud rates: 125k, 250k, and 500k bps.
• Compatible with standard DLL and library sets for custom software integration.

Applications

The SST-DN4-104-2 is widely utilized in industrial automation sectors requiring reliable fieldbus communication, including automotive assembly lines, water treatment facilities, and complex material handling systems. It is ideal for applications requiring multi-network bridging or redundant network configurations within a single PCI slot.

Installation Guidelines

• Ensure the host system is powered down before inserting or removing the interface card from the PCI slot.
• Handle the module by the edges to prevent electrostatic discharge (ESD) damage to sensitive components.
• Ensure the card is firmly seated in the PCI slot and secured with the mounting screw to prevent vibration-induced disconnects.
• Use shielded twisted-pair cabling for DeviceNet connections to minimize EMI interference.
• Verify that the network termination resistors are correctly installed at both ends of the DeviceNet trunk line.
• Maintain adequate ventilation within the industrial PC enclosure to ensure the operating temperature remains below 60 deg C.

FAQ

Is the SST-DN4-104-2 compatible with older SST-DN3-104-2 applications?
Yes, the SST-DN4-104-2 is designed as a direct replacement for the legacy SST-DN3-104-2 and maintains compatibility with existing software libraries and DLLs.

Does this card require external power?
The card is powered via the PCI bus; however, the DeviceNet network itself requires a separate 24 VDC power supply for the fieldbus devices.
