VIBRO-METER VM600 204-040-100-012 Module

The 204-040-100-012 (IOC4T) is a high-performance 4-channel vibration & displacement monitoring module for the VM600 machinery protection 

and condition monitoring system, manufactured by VIBRO-METER (Spectris/Meggitt). It interfaces with IEPE/ICP accelerometers, 

eddy-current displacement probes, and speed sensors, providing real-time vibration analysis, overspeed protection, 

and alarm logic for critical rotating equipment (turbines, compressors, generators). Hot-swappable and fully compliant with API 670,

 it ensures continuous, reliable operation in harsh industrial environments.
