DESCRIPTION

Introduction

The VM600Mk2 MPC4Mk2 + IOC4Mk2 machinery 

protection and condition monitoring module is 

designed for operation with the second 

generation of VM600Mk2 rack-based machinery 

protection system (MPS), from Meggitt’s 

vibro-meter® product line. The VM600Mk2

MPC4Mk2 + IOC4Mk2 module consists of 

processing and input/output (interface) modules 

that provide 4 dynamic and 2 auxiliary channels 

of machinery protection and optional condition 

monitoring in VM600Mk2 systems.

VM600Mk2 rack-based monitoring systems

The vibro-meter® VM600Mk2 rack-based 

monitoring system is the evolution of Meggitt’s 

solution for the protection and monitoring of 

rotating machinery used in the power generation 

and oil & gas industries. VM600Mk2 solutions are 

recommended when a centralised monitoring 

system with a medium to large number of 

measurement points (channels) is required. It is 

typically used for the monitoring and/or 

protection of larger machinery such as gas, 

steam and hydro turbines, and generators, 

smaller machines such as compressors, fans, 

motors, pumps and propellers, as well as balanceof-plant (BOP) equipment.

A VM600Mk2 system consists of a 19" rack, a rack 

power supply and one or more monitoring 

modules. Optionally, relay modules and rack 

controller and communications interface 

modules can also be included.

Two types of rack are available: a VM600Mk2

system rack (ABE04x, 6U) that can house up to 

twelve monitoring modules, and a VM600Mk2

slimline rack (ABE056, 1U) that can house one 

monitoring module. The racks are typically 

mounted in standard 19" rack cabinets or 

enclosures installed in an equipment room.

Different VM600Mk2 monitoring modules are 

available for machinery protection, condition 

monitoring and/or combustion monitoring 

applications. For example, the 

MPC4Mk2 + IOC4Mk2 module supports both 

machinery protection and condition monitoring, 

the XMV16 + XIO16T module supports extended 

condition monitoring for vibration and the 

XMC16 + XIO16T module supports extended 

condition monitoring for combustion.

Note: For the MPC4Mk2 + IOC4Mk2 machinery 

protection and condition monitoring module, the 

machinery protection functionality is available by 

default, while the condition monitoring 

functionality is optional and depends on the 

purchased VibroSight® software license.

The RLC16Mk2 relay module is an optional module 

used to provide additional relays when the four 

user-configurable relays per MPC4Mk2 + IOC4Mk2

module are not sufficient for an application.

The CPUMMk2 + IOCNMk2 rack controller and 

communications interface module is an optional 

module used to provide additional VM600Mk2

system functionality such as fieldbus 

communications; module data aggregation, 

processing and sharing; rack and/or fieldbus 

communications redundancy; front-panel alarm 

reset (AR); MPS rack (CPUx) security; system event 

and measurement event logging.

VM600Mk2 rack-based monitoring systems 

complement the VibroSmart® distributed 

monitoring systems that are also available from 

Meggitt’s vibro-meter® product line, and are 

compatible with the same VibroSight® machinery 

monitoring software suite.
