1. Core Functions & Operating Role

Unlike general-purpose I/O modules, the PVIB series is engineered specifically for mechanical condition monitoring. Key responsibilities include:

• High-accuracy acquisition of vibration, axial position, and rotor dynamic signals

• Real-time monitoring for early detection of mechanical anomalies

• Data preprocessing for diagnostics and performance analysis

• Continuous communication with Mark VIe controllers for protection and control logic

• Enhancing plant reliability by identifying imbalance, misalignment, bearing wear, and instability

This makes the module an essential component in critical rotating machinery systems.
