Description
The Woodward SST-PB3-PCU-2 is a high-performance PROFIBUS communication interface card designed for universal PCI bus integration. This module enables industrial computers to interface directly with PROFIBUS DP networks, supporting both Master and Slave configurations. By offloading protocol processing from the host CPU to an onboard processor, the SST-PB3-PCU-2 ensures maximum system stability, reduces network latency, and provides reliable, deterministic data exchange for critical industrial applications.
Features
-
Universal PCI Compatibility: Supports both 3.3 V and 5 V signaling environments.
-
Dual-Channel Capability: Facilitates complex network topologies and high-throughput data exchange.
-
Protocol Offloading: Onboard processor manages the PROFIBUS stack, minimizing host CPU overhead.
-
High-Speed Communication: Supports PROFIBUS DP-V0 and DP-V1 protocols with transmission rates up to 12 Mbps.
-
Robust Design: Features electrical isolation to protect the host system from ground loops and industrial electrical interference.
Applications
This interface card is engineered for demanding industrial environments, including power generation plants, petrochemical refineries, and mining automation systems. It is ideal for scenarios where precise timing and deterministic communication are required for process control and monitoring.

Installation Guidelines
-
ESD Precautions: Always use an anti-static wrist strap and handle the card by its edges to prevent electrostatic discharge damage.
-
Power-Down: Ensure the host industrial computer is completely powered down and disconnected from the AC supply before inserting or removing the PCI card.
-
Slot Seating: Ensure the card is firmly seated in the PCI slot and secured with the chassis screw to prevent vibration-induced disconnects.
-
Cable Routing: Keep PROFIBUS communication cables away from high-voltage power lines and high-EMI sources to maintain signal integrity.
-
Thermal Management: Ensure the host computer chassis has adequate airflow to support the card's operating temperature range.
FAQ
