Woodward DN3-PCI-1-E DeviceNet Interface Card

Description

The Woodward DN3-PCI-1-E is a high-speed communication interface card designed to facilitate seamless data exchange between industrial control systems and DeviceNet networks. This module serves as a critical bridge for real-time monitoring and control in demanding environments such as power generation facilities, oil refineries, and large-scale industrial automation plants. By offloading complex protocol management from the main processor, the DN3-PCI-1-E ensures deterministic network performance, helping to maintain system stability and reduce unplanned downtime.

Features

• High-speed DeviceNet communication interface.
• Supports both master and slave modes for flexible network configuration.
• Onboard firmware handles the protocol stack to ensure low-latency data throughput.
• Galvanic isolation (500 VDC) to protect host hardware from electrical transients and field-side noise.
• Ruggedized hardware design suitable for high-vibration industrial environments.
• Optimized for integration into industrial PC-based control platforms using PCI bus architecture.

Applications

The DN3-PCI-1-E is intended for use in critical control loops where high-speed I/O synchronization and robust diagnostic reporting are required. It is commonly deployed in systems requiring reliable communication between industrial PCs and field devices on a DeviceNet network.

Technical Specifications

Installation Guidelines

• Ensure the host industrial PC is powered down before inserting or removing the interface card.
• Handle the module using proper ESD (electrostatic discharge) precautions to prevent damage to internal components.
• Ensure the card is firmly seated in the PCI slot and secured with the appropriate mounting hardware to maintain signal integrity in high-vibration environments.
• Route DeviceNet cabling away from high-voltage power lines and sources of significant electromagnetic interference (EMI) to ensure reliable communication.
• Verify that the DeviceNet network is properly terminated at both ends of the trunk line according to standard specifications.
