Key Features

• Dual-Channel Rack Efficiency: Monitors two separate vibration points on a single card, maximizing the density of the 3300 rack and reducing the overall hardware footprint.

• API 670 Compliant Protection: Engineered to meet the rigorous global standards for machinery protection, ensuring reliable automatic shutdown logic for critical plant infrastructure.

• Buffered Transducer Outputs: Features front-panel or terminal-accessible buffered outputs, allowing maintenance teams to connect portable vibration analyzers without interrupting the primary protection loop.

• Programmable Alarm Logic: Supports user-defined Alert and Danger setpoints, providing the flexibility to tailor protection strategies to the specific mechanical tolerances of the machine.

• Rugged Industrial Build: The PCB is treated to resist the thermal stress and electrical noise common in power generation and petrochemical control environments.

• Advanced Diagnostic Support: Delivers continuous 4-20mA or voltage-proportional outputs, facilitating long-term trending and early detection of imbalance, misalignment, or bearing degradation.
