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.
