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.
