Decreases capital equipment costs

The Classic I/O subsystem includes:

✔

I/O interface carrier (a DIN rail surface mounted)

on which all I/O related components are

installed.

Decreases installation time and expense

Increases productivity

✔

Bulk AC to 24 VDC power supply for field

devices.

Introduction

Classic I/O is a modular subsystem that offers

flexibility during installation. It’s designed to be

installed in the field, near your devices. Classic I/O is

equipped with function and field wiring protection

keys to ensure that the correct I/O card is always

plugged into the corresponding terminal block.

Modularity, protection keys, and plug and play

capabilities make DeltaV Classic I/O a smart choice

for your process control system.

✔

An I/O interface consisting of an I/O card and an

I/O terminal block.

✔

A variety of analog and discrete I/O cards

enclosed in a common form factor that easily

plugs into the I/O interface carrier.

✔

A variety of I/O terminal blocks mounted on the

I/O interface carrier that can be pre-wired before

I/O card installation.

Benefits

Decreases capital equipment costs.

Full system modularity. The Classic I/O subsystem

was designed with your investment in mind. All

components are fully modular and may be installable

under power. 1 You add I/O interface carriers and I/O

interfaces in groups of 8 channels as you need

them. The modular design enables you to purchase

the exact amount of I/O cards, 8-wide carriers,

power/controllers, and 2-wide carriers you need and

add more DeltaV I/O as your system grows.

Reduced system footprint. The DeltaV system’s

state-of-the-art form factor design of the I/O

components enables you to mount the I/O interface

carrier in a junction box in the field so you

significantly reduce the footprint of your equipment

and increase valuable control room space for other

uses.

Decreases installation time and

expense.

Plug-and-play installation saves money. All

Classic I/O components plug into the I/O interface

carrier. You can install the I/O interface carriers to

manage anticipated growth and postpone the I/O

interfaces until you’re ready to install your additional

field devices.

Phased installation saves time. As soon as you

mount the I/O interface carrier, you’re ready to begin

installing the field devices. I/O terminal blocks plug

directly onto the I/O interface carrier. There is no

need to have the I/O cards installed.

Installation. Save on wiring expenses by installing

Classic I/O in the field, near the actual field devices.

Mounting the controller with the I/O further reduces

your wiring expenditures by eliminating the need for

long runs of multi-cores. The integrated design of

the I/O subsystem can eliminate the need for

marshaling panels. This saves you even more in

your total capital costs.

The provision of in-line fuses and bussed power

saves on installation costs compared with external

fuses and power distribution.

Classic I/O terminal block.

Keys. Classic I/O interfaces and terminal blocks

have I/O function keys. These keys ensure that the

correct I/O card is always plugged into the

corresponding terminal block. It’s incredibly easy to

use and gives you time to do more.

1 Refer to Zone 2 installation instructions (12P2046)

and/or Class 1 Division 2 installation instructions

(12P1293) for details.

This design enables you to initially install Classic I/O

quickly and efficiently. When you need to replace an

I/O card, the function key design ensures that you

will always install it correctly. This keying system

provides a safety measure by preventing the wrong

I/O interface’s being installed.

Product Description and Specification

I/O Cards

A variety of analog and discrete I/O cards is

available to meet your specific requirements. All I/O

cards are enclosed in a common form factor that

plugs into the I/O interface carrier. The housing is

clearly labeled with the enclosed I/O card type.

Clearly visible LEDs on the top of the I/O card

display the power, error, and status to the channels

included in the I/O card.

Increases productivity.

Real-time, online equipment additions. Online

addition of new I/O interfaces means your process

does not get interrupted. As new equipment is

added, the DeltaV Explorer acknowledges it and

assigns it basic configuration.

We have met ISA G3 corrosion specifications by the

careful selection of superior electronic components

and the use of conformal coating.

For slow pulse applications (< 125 Hz) any discrete

input card can be used. The most commonly used

discrete input cards for pulse applications are the

discrete input 24 VDC.
