DESCRIPTION
Introduction
The VM600Mk2 RLC16Mk2 relay modules are
designed for operation with the second generation of
VM600Mk2 rack-based machinery monitoring
system, from Parker Meggitt’s vibro-meter ® product
line. A VM600Mk2 RLC16Mk2 module consists of a
single module that provides 16 additional user
configurable relays (per module) in VM600Mk2
systems, for when the 4 relays provided by a
MPC4Mk2 + IOC4Mk2 module are not enough.
Note: The VM600Mk2 RLC16Mk2 module is available in
a standard version (RLC16Mk2) and a SIL safety
version (RLC16Mk2 SIL).

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 energy industry. 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
balance-of-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.
