Vibro-meter 620-002-000-113 620-003-111-112 VM600 XIO16T

Vibro-meter 620-002-000-113, 620-003-111-112, and VM600 XIO16T are key components of Meggitt’s VM600Mk2/VM600 rack-based machinery condition monitoring systems. The 620-series models (620-002-000-113, 620-003-111-112) typically function as sensor interface or signal conditioning units, while the VM600 XIO16T serves as a dedicated input/output (I/O) interface module—all designed to enable high-precision data acquisition for machinery vibration, combustion, or operational condition monitoring.

Description

1. General Overview & Core Function

Component Model Primary Function Compatibility
620-002-000-113 Analog sensor signal conditioning (e.g., for accelerometers, velocity sensors) – amplifies, filters, and isolates raw sensor signals to ensure signal integrity. VM600Mk2/VM600 rack systems; pairs with XMx16 processing modules.
620-003-111-112 Specialized signal interface for tachometer/proximity probes – converts rotational speed or position signals (e.g., from eddy-current probes) into digital data for speed monitoring and phase analysis. VM600Mk2/VM600 rack systems; supports tachometer-based machinery diagnostics.
VM600 XIO16T Integrated I/O module for the XMx16 processing module – provides 16 dynamic signal input channels and 4 dedicated tachometer input channels; enables connection to external sensors and communication with the rack backplane. Exclusive to VM600Mk2/VM600 racks (ABE04x standard rack, ABE056 slimline rack); pairs with XMV16 (vibration monitoring) or XMC16 (combustion monitoring) processing modules.
