The VM600Mk2 RLC16Mk2 relay 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 RLC16Mk2 is a second generation module that provides 16 additional relays per module 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.

RLC16 Mk2

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.
