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.
