Vibro-meter MPC4 200-510-078-115 Meggitt Sensing Systems

Description

Processed dynamic (vibration) and velocity signals are available as analog outputs

at the rear of the rack (on the front panel of the IOC4T).

Voltage signals (0 to 10 V) and current signals (4 to 20 mA) are available.

The MPC4 performs self-tests and diagnostic procedures at power-up.

In addition, the card's built-in “OK system” continuously monitors the signal level provided

by the measurement chain (sensors and/or signal conditioners) and indicates any problems

caused by broken transmission lines, faulty sensors or signal conditioners.

An LED on the front panel of the MPC4 indicates whether a processing or hardware error has occurred.

A further six LEDs, one for each input channel, indicate whether the OK system has detected

a fault and whether an alarm has occurred on the channel.

There are three versions of the MPC4 card: the “standard” version, the “circuit independent” version,

and the “safe” (SIL) version, all of which use the appropriate IOC4T input /output cards as card pairs.

Different versions of the MPC4 card

There are different versions of the MPC4 card, including “Standard”, “Circuit Independent”

and “Secure” (SIL) versions.

In addition, some versions have a conformal coating applied to the card's circuitry to provide additional

environmental protection against chemicals, dust, moisture and temperature extremes.

Both the “Standard” version and the “Safety” (SIL) version of the MPC4 card are certified to

IEC 61508 and ISO 13849 for use in functional safety environments such as SIL 1 according

to IEC 61508 and ISO 13849-1 for PL c.

The “standard” MPC4 card is the original version and supports all functions and processing modes.

The “standard” MPC4 is suitable for safety systems using the VM600 rack. 

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.
