Description
The Woodward SST-PB3-PCU is a robust communication interface card engineered for PCI bus-based industrial computing systems. This module serves as a bridge for high-speed data exchange, allowing industrial PCs to participate in PROFIBUS DP and MPI networks. By offloading protocol management to an internal processor, the card maintains deterministic communication performance, making it a reliable component for demanding control applications in sectors such as energy production, petrochemical processing, and automated manufacturing.
Features
- Integrated on-board processor for dedicated PROFIBUS protocol stack handling, reducing host CPU utilization.
- Supports DP-V0, DP-V1, and MPI communication standards for versatile network integration.
- Galvanic isolation provided to mitigate the impact of electrical interference and transient voltages.
- Universal PCI interface design compatible with both 3.3 V and 5 V bus architectures.
- Optimized for low-latency data throughput in critical industrial automation environments.
Applications
This interface card is typically deployed in industrial control systems requiring reliable connectivity between supervisory PCs and PROFIBUS-enabled field devices. Its primary use cases include data acquisition, supervisory control, and synchronization of distributed I/O across large-scale plant networks.
