A6410 | Emerson EPRO | VM600 Speed and Phase Reference Card

Product Description

Precision Speed and Phase Reference Monitoring

The Emerson EPRO A6410 is a high-performance Dual Channel Speed and Phase Reference Module engineered for the VM600 machinery protection system. This module is essential for rotating machinery—such as steam turbines, gas turbines, and high-speed compressors—providing the precise timing signals required for advanced vibration analysis and overspeed protection. By capturing and processing signals from proximity probes or magnetic pickups, the A6410 delivers a high-resolution once-per-turn reference pulse, which is critical for shaft position monitoring and diagnostic synchronization.

Advanced Signal Processing and Redundancy

The A6410 features a dual-channel architecture, allowing for independent monitoring of two separate speed sources or redundant monitoring of a single shaft. This design ensures that phase reference detection remains accurate within ±0.1% of the measured speed, even in high-EMI industrial environments. The module integrates seamlessly with vibration monitoring units (A6310) and overspeed protection modules (A6370D), forming a comprehensive machinery protection solution that meets stringent API 670 standards. Its high-resolution digital processing allows for reliable detection across a wide measurement range, from slow-roll startup speeds up to 60,000 RPM.
