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.

Both power supplies support a wide input voltage range.

The rack has an integrated backplane that provides electrical interconnection between the integrated power supply (RPS1U) and the installed VM600Mk2/VM600 modules (cards).

The rack also has a power check relay on the rear of the rack to indicate if the integrated power supply is functioning properly.

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.

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.

For example, in a typical application, these relays can be used to signal an MPC4 fault or a problem detected by the common alarms (Sensor Normal, Alarm, and Hazard).

In addition, 32 digital signals representing alarms are transmitted to the rack backplane and can be used by the optional RLC16 Relay Card and/or IRC4 Intelligent Relay Card (with optional jumpers) mounted in the rack.

Description

MPC4 Card

The MPC4 Machine Protection Card is the centerpiece of the VM600 series of Machine Protection Systems (MPS) from Meggitt’s Vibrometer® product line. The card is extremely versatile, capable of measuring and monitoring up to four dynamic signal inputs and two velocity inputs simultaneously.

The dynamic signal inputs are fully programmable and can accept the following signals

acceleration, velocity and displacement (proximity) signals. On-board multi-channel processing allows measurement of a wide range of physical parameters including relative and absolute vibration, Smax, eccentricity, thrust position, absolute and differential case expansion, displacement and dynamic pressure.

Digital processing includes digital filtering, integration or differentiation (if required), rectification (RMS, average, true peak, or true peak-to-peak), order tracking (amplitude and phase), and measurement of transducer-to-target clearance.

The speed (tachometer) input accepts signals from a variety of speed sensors, including systems based on proximity probes, magnetic pulse pickup sensors, or TTL signals. Fractional tachometer ratios are also supported.
