VM600Mk2/VM600 Mechanical Protection and/or Condition Monitoring Systems

The VM600Mk2/VM600 ABE056 slimline rack is used to house the hardware for

the VM600Mk2/VM600 series of machine protection and/or condition monitoring systems in the Vibrometer® product line.

The VM600Mk2/VM600 ABE056 slimline rack has a standard height of 1U and provides mounting

space (rack slots) for a single wide VM600Mk2/VM600 processing module (card pair) and a relay module (card).

This rack is particularly suitable for industrial environments where the equipment must be permanently installed in a 19-inch cabinet or panel.

Different versions of the integrated RPS1U power supply can power the VM600Mk2/VM600

ABE056 slimline racks from an external AC or DC power supply.

Description

AMC8 Card

The AMC8 is an analog monitoring card designed for use in the VM600 rack-mounted system

in the Meggitt Vibrometer® product family for machinery monitoring and protection applications.

This versatile card is capable of measuring and monitoring up to eight analog signal inputs simultaneously.

The AMC8 card is available in two versions: a “standard” version and a “circuit independent” version,

both of which are available as card pairs using the corresponding IOC8T input/output card.

The AMC8 card is mounted on the front of the VM600 rack (ABE04x or ABE056) and the IOC8T I/O card is mounted on the rear.

Both cards connect directly to the rack backplane via two connectors.

A pair of AMC8/IOC8T cards provides eight channels of temperature monitoring that accept resistance

temperature detector (RTD) and thermocouple (TC) temperature inputs as well as process inputs.

The source and type of each channel is selectable during card configuration.

Cold Junction Compensation (CJC) sensor processing is used for the thermocouple temperature

channel and can be used for two of the eight channels, also selectable during card configuration.

All inputs are conditioned and compared to user-configurable alarms that are defined through Meggitt’s VM600 MPSx software.

A pair of AMC8/IOC8T cards is configured (i.e. operated independently) via the RS-232 port on the front panel of the relevant AMC8 card.

The AMC8 card also provides access to the CPUx card (ABE04x only) in slot 0 of the VM600 rack via the VME bus.

These interfaces allow the operator to configure the VM600 card, access measurements,

view detailed board status, upload firmware updates, and more.

The AMC8 card can drive the four local relays on the IOC8T card, as well as any of the 16 relays

on the RLC16 card using the VM600 rack’s raw bus and/or open collector (OC) bus.

These cards also provide analog signal outputs based on current (0 to 25 mA). Voltage outputs are also supported.

Discrete Signal Interface (DSI) inputs

Description

IOC4T Card

The IOC4T Input/Output card is the signal interface for Meggitt’s VM600 series MPC4 machine protection card.

It is mounted on the rear of the VM600 rack and connects directly to the rack backplane via two connectors.

Each IOC4T card is associated with the corresponding MPC4 card and is mounted directly to the rear of the VM600 rack (ABE04x or ABE056).

The IOC4T operates in slave mode and communicates with the MPC4 through connector P2 using the Industrial Packet (IP) interface.

The front panel of the IOC4T (rear of the VM600 frame) contains terminal strip connectors

for connecting the transmission cables from the measurement chain (sensors and/or signal conditioners).

The threaded terminal connectors are also used to input all signals from any

external control system and output all signals to any external control system.

The IOC4T card protects all inputs and outputs from electromagnetic interference (EMI)

and signal surges and complies with electromagnetic compatibility (EMC) standards.

The IOC4T connects raw dynamic (vibration) and velocity signals from sensors to the MPC4.

These signals are processed and passed back to the IOC4T and made available on its front panel (rear of the VM600) terminal strip.

For dynamic signals, four on-board digital-to-analog converters (DACs) provide calibrated signal outputs in the 0 to 10 V range.

In addition, four on-board voltage-to-current converters provide current output signals in the 4 to 20 mA range (jumper optional).

The IOC4T contains four local relays that can be used for any specific alarm signal under software control.

Features

System isolation

The VM600Mk2 uses a single type of card (MPC4Mk2) for monitoring and condition monitoring.

However, these functions are tightly segregated to ensure API 670 compliance and reduce costs.

A separate (optional) XMV16 condition monitoring card is available for applications with a large number of channels.

High channel density

The standalone VM600Mk2 protection card has 4 input channels, but each VM600 can be expanded

to a maximum of 48 input channels Mk2 racks, allowing vibration protection to be extended to the most demanding rotating machinery.

Advanced Monitoring

The stand-alone VM600Mk2 condition monitoring card offers 16 dynamic channels and 4 tachometer channels,

which can all be independently configured to provide unrivaled accuracy and reliability.
