Emerson’s Automation Solutions Power and Water project organization includes a dedicated team

focused on mechanical solutions and services that improve equipment operation, performance and

reliability for fossil, combined cycle, simple cycle, hydro, renewable or nuclear power generators.   

Emerson’s mechanical solutions group provides a complete range of capabilities — everything from full 

conversion of older, low-pressure, mechanical governor controls to installation of modern, high-pressure

hydraulic controls, trip system upgrades, electronic overspeed protection and mechanical bolt

replacement to simple LVDT, servo valve, speed sensing and vibration monitoring system replacements.  

The team can act as a Main Automation Contractor (MAC-EPC) to manage a project with full-scope

mechanical and electrical installation and commissioning services. 

In addition to the team’s extensive experience designing, fabricating and testing both complete hydraulic

and electric actuator systems for large steam turbines, they have also completed hundreds of feed-pump

turbine control modernizations, turbine protection system upgrades and enhancements, hydro turbine

mechanical-to electronic governor conversions and hydraulic actuator rebuilds.

System Compatibility

M-series I/O carriers are not physically compatible with

S-series controller carriers, except when used with the

DeltaV SIS Adapter.

The M-series controllers cannot detect the difference between

an 8-wide and a 4-wide carrier. If a 4-wide carrier is used,

the four I/O slots after the slots on the carrier will be lost to

an M-series controller. If either a 4-wide or 8 wide carrier is

connected after a 4-wide carrier, the first slot number will

be 5 numbers higher than the last slot on the 4-wide carrier.

For example, if a controller has a 4-wide carrier followed by

an 8-wide carrier, the slots on the 4-wide carrier will be

1. 2. 3. and 4. and the slots on the 8-wide carrier will be

slots 9. 10. 11. 12. 13. 14. 15. 16. The PK Controller does

not have this behavior because it can distinguish between

a 4-wide and an 8-wide carrier. However, there is still a limit

of 8 total carriers (4-wides and/or 8-wides) on any controller.

The horizontal carrier family also offers a 2-wide power carrier.

Use this carrier, along with one or two system power supplies to

provide 12 V DC local bus power connected through the carrier

extenders. There are two 12 V DC output connections powered

by either supply. For redundant power, ensure that the power

demand is within the output range of one system power supply.

With the introduction of the PK controller, a 4 wide I/O carrier

is available for use with M-series I/O cards when a smaller

footprint for the hardware is required. The 4-wide carrier

allows for individual field power per card slot and is ideal

if separate field power is required for redundant I/O cards.

Benefits

Modular design allows flexible installation. A T- type DIN

rail is all you need to mount the power/controller carrier into

place. The I/O interface carrier plugs on to the power/controller

carrier. Simply plug your I/O terminal blocks into the carrier.

The DeltaV system’s modular design approach allows you to

add I/O carriers as you need them.

Allows you to expand online. Additional 8-wide carriers

may be added online as desired. Carrier extenders give you

the flexibility to install I/O carriers in multiple rows with 1.2.

3 or 4 carriers per row.

Integrated power distribution. Controller and I/O interface

power distribution is integrated into the carriers to reduce and

simplify power and grounding. Carriers also have integrated

shield ground bar to isolate and drain field noise away from

system power.

• Modular design allows flexible installation

• Allows you to expand online

• Integrated power distribution

Introduction

Get your I/O subsystem up and running efficiently with the

DeltaV™ horizontal mount I/O carriers. The power/controller

carrier contains internal power buses. You don’t need to use

external cabling to connect the system power supply to the

DeltaV controller and the I/O interface carriers.

The power/controller and I/O carriers are modular.

Purchase only what you need but be assured that as your

system grows you can add plug-and-play carriers—Easy!

With the introduction of DeltaV SIS the left one-wide

and right one-wide dual carrier extenders have two,

44-pin D- Shell connectors which supports dual cables for

a fault tolerant configuration. The A and B connectors are

in parallel so either port may be used. The new dual carrier

extenders are a pre-requisite for DeltaV SIS as these also

provide extension of the redundant safety bus used by the

Safety Logic Solvers. The VerticalPLUS mount carriers also

support dual cables and can be used with DeltaV SIS.

Refer to the new VerticalPLUS Carrier Product Data Sheet

for more details on these new carriers.

The horizontal carrier family also offers a 2-wide power carrier.

Use this carrier, along with one or two system power supplies to

provide 12 V DC local bus power connected through the carrier

extenders. There are two 12 V DC output connections powered

by either supply. For redundant power, ensure that the power

demand is within the output range of one system power supply.

Product Description

The I/O interface carrier plugs on to the power/controller

carrier. The power/controller carrier supplies the system

power and communications between the I/O interfaces and

the controller. The controller processes the I/O interface

information. An additional power/controller carrier is required

for use with redundant controllers.

Mount your interface carrier on a T-type DIN rail. The I/O

interface carrier includes the connections for the bulk 24 V DC

field instrument power, I/O interfaces, and terminal blocks.

Each I/O interface carrier is equipped with a connector that

allows an additional I/O interface carrier to be plugged on to it.

Up to 64 I/O interfaces on eight 8-wide I/O interface carriers are

supported by a single I/O subsystem. For the horizontal-mount

solution, 1-wide local bus extenders allow you to continue

the I/O bus on a different row of carriers. There are two types

of 8-wide I/O interface carriers available. They both have

connectors for field power on the top of the carrier. The original

carrier connects each set of field power terminals to two I/O

cards, and the other option have individual field power per card

slot and is ideal if separate field power is required for redundant

I/O cards.

The health and status of both SLS 1508 Logic Solvers and their channels are

available in the diagnostics explorer.

When one of a redundant pair of SLS 1508 Logic Solversis removed online there

is no disturbance to the process.

When the missing SLS 1508 Logic Solver is replaced with another SLS 1508 Logic Solver,

the new SLS 1508 Logic Solver completes its power-up self-tests before the

active Logic Solver cross-loads the current database.

In safe areas, failed SLS 1508 Logic Solvers can be replaced under power.

In hazardous areas,appropriate installation procedures must be followed.

Automatic proof testing can be selected on a redundant pairof SLS 1508 Logic Solvers.

The desired proof-test interval is set in the configuration and the SLS 1508 Logic Solvers perform

the proof test automatically. A warning is given to the operator before

the automatic proof test is started.
