Features, benefi ts, and functions

• Complete motor protection and control in a single compact case

reduces panel space requirements and wiring costs

• Microprocessor design with self diagnostics eliminates calibration

and reduces installation, commissioning, and maintenance

• Programmable stop 2–20% of PCT

• Intel-I-Trip overload protection develops customized curve from

manufacturer’s supplied motor data

tics based on motor temperature when motor RTDs are

connected through an optional URTD module

• Meets UL 1053 ground fault protection standards that eliminates

the need for a separate ground relay saving cost, space, wiring,

and time

displayed either locally or remotely

• Event log provides motor operating records for the most recent

20 trip or alarm events with date and time stamping. This

information can improve troubleshooting and reduce downtime

START/STOP and set point changes to provide a log of motor

operation with date and time stamping

coordination. This feature can be used to develop protection

settings on old motors where data is not available

software simplifies setting, configuration, monitoring, commis

sioning, and data retrieval either locally or remotely

removal and replacement

The MTL4854 mounts on the same range of backplane as

the MTL4850 but includes four HART modems that enable

simultaneous communications with connected field devices to

be carried out.

The primary application for this is to enable monitoring of other

channels to continue while one channel is being used for valve

positioner diagnostics.

The benefits of utilising these powerful software packages online

include:

• Reduced commissioning time and costs

• Reduced maintenance costs

• Reduced documentation

• Reduced process downtime

The MTL4850/54 offers connectivity to a comprehensive range

of FDT based software packages via the comms Device Type

Manager (DTM). The DTM can be downloaded from

www.mtl-inst.com. Other software packages work with the

MTL4850/54 through custom software drivers or by the inclusion

of the device description (DD) file for the MTL multiplexers.

Connectivity to HART Configuration and Instrument

Management Software

The online access to the information contained within HART

devices allows users to diagnose field device troubles before they

lead to costly problems. Software can capture and use diagnostic

data from HART field instruments via the MTL HART connection

hardware. This allows users to realise the full potential of their

field devices to optimise plant assets, which results in significant

operations improvement and direct maintenance savings.

IMS products provide essential configuration, calibration,

monitoring and maintenance history functions for conventional

analogue (4-20 mA) and HART protocol compatible smart process

instruments and field devices. They deliver powerful tools to meet

the need for standardised instrument maintenance procedures

and record keeping mandated by some quality standards and

regulatory bodies.

The MTL4850 HART multiplexer provides a simple interface

between smart devices in the field, control/safety systems and

HART® instrument management software running on a PC.

The system is based on 32-channel modularity to provide a

compact, easily configurable and expandable system. Using a

standard RS485 serial link, up to 2016 individual HART devices can

be connected to a single network.

For the optimum solution, the modules mount directly to either a

range of generic or customised connection units/backplanes.

The MTL4850 is certified for the use with safety related sub

systems to IEC 61508. and is the first choice of HART multiplexer

for these applications. It can be connected to signal loops that

are part of safety instrumented functions up to SIL3.

With the fixed modularity of 32 channels, the speed of scanning

field devices and responsiveness to PC software requests is

optimised when compared to master/slave configurations.

the MTL4850 but includes four HART modems that enable

simultaneous communications with connected field devices to

MP-4000 motor relay

The MP-4000 motor relay is generally used on

a motor starter or a breaker used for a motor

load. The MP-4000 motor relay provides the

intelligence to protect and control the motor

against abnormal operating conditions. It monitors

the currents from either a 5A or a 1A secondary

of a CT circuit. Ground current may be obtained

from either a ground CT or from the residual

connection of the phase CTs. It provides a Form C

contact output for controlling the starter contacts

or breaker operation.The protection functions are listed below:
