Emerson The DeltaV horizontal-mount 8-wide I/O interface carrier with individual field power per I/O card

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.

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.

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.
