DESCRIPTION (continued)

Different versions of the MPC4Mk2 +  IOC4Mk2

module

The MPC4Mk2 + IOC4Mk2 machinery protection and

condition monitoring module is available in different

versions, as follows:

• MPC4Mk2 + IOC4Mk2 – this is the standard

version of the module, suitable for most

applications.

• MPC4Mk2 + IOC4Mk2 SIL – this is the SIL safety

version of the module, suitable for critical

applications demanding the highest level of

protection.

The MPC4Mk2 + IOC4Mk2 (standard) is the original

version of the module and supports all features and

processing functions.

The MPC4Mk2 SIL + IOC4Mk2 SIL is a version of the

module optimised for use in safety-related

applications (functional-safety contexts).

Accordingly, it has been designed in accordance with

the IEC 61508 “functional safety” standard and is

certified as SIL 2 capable by design.

In general, the MPC4Mk2 SIL + IOC4Mk2 SIL module

supports the same signal processing functions and

measurements as the MPC4Mk2 + IOC4Mk2

(standard) module but SIL versions of modules are

visually distinct and feature some important

differences in order to meet the strict requirements of

SIL safety systems.

For example, the MPC4Mk2 SIL module uses three

electronics processing modules in order to help

ensure that measurements can always be trusted

(compared to one processing module for the

MPC4Mk2 module) and offers more complete

separation of machinery protection system (MPS)

and condition monitoring system (CMS) functionality

so that the safety function is never compromised. The

MPC4Mk2 SIL also includes more comprehensive

diagnostics (BIST). For a more detailed comparison,

see Differences between standard and SIL

versions of the VM600Mk2 MPC4Mk2 +

IOC4Mk2 (and RLC16Mk2) modules starting on

page 6.

In addition, some versions of VM600Mk2 modules are

also available with a conformal coating in order to

provide additional environmental protection

Either one or two VM600Mk2/ VM600 RPS6U rack

power supplies can be installed in a VM600Mk2/

VM600 ABE04x system rack. A rack with one

RPS6U power supply (330 W version) supports the

power requirements for a full rack of modules

(cards) in applications with operating

temperatures up to 50 °C (122 °F).

Alternatively, a rack can have two RPS6U power

supplies installed in order to either support rack

power supply redundancy or in order to supply

power to the modules (cards) non-redundantly

over a wider range of environmental conditions.

A VM600Mk2/ VM600 ABE04x system rack with two

RPS6U power supplies installed can operate

redundantly (that is, with rack power supply

redundancy) for a full rack of modules (cards).

This means that if one RPS6U fails, the other will

provide 100 % of the rack’s power requirement so

that the rack will continue to operate, thereby

increasing the availability of the machinery

monitoring system.

Note: This is known as a redundant RPS6U rack

power supply configuration.

A VM600Mk2/ VM600 ABE04x system rack with two

RPS6U power supplies installed can also operate

non-redundantly (that is, without rack power

supply redundancy). Typically, this is only

necessary for a full rack of modules (cards) in

applications with operating temperatures above

50 °C (122 °F), where RPS6U output power derating

is required.

Note: Even though two RPS6U rack power supplies

are installed in the rack, this is not a redundant

RPS6U rack power supply configuration
