Emerson DeltaV S-series Traditional I/O Introduction

DeltaV™ S-series Traditional I/O

• Modular and flexible construction

• Reduced installation time and expense

• Easy online expansion

• Field-mounted capable hardware

• 1:1 Redundancy for traditional I/O

• Plug-and-Play I/O

Introduction

S-series traditional I/O interfaces provide improved ease

of installation with the same proven features of M-series

I/O interfaces. This modular I/O subsystem offers flexibility

during installation and is designed for extreme environmental

conditions of field installations. S-series traditional I/O is

equipped with a snap-in retention system for quick installation.

The I/O interfaces can be installed in any of the possible

64 slots.

All wiring is through the carriers and terminal blocks so that

modules can easily be removed without disconnecting any

wires. Modularity, fast installation, online expansion, and

environmentally robust hardware make DeltaV S-series

traditional I/O a smart choice for your process control system.

Benefits

Modular and flexible construction: The S-series traditional

I/O subsystem is designed with your investment in mind.

Each controller supports up to eight I/O carriers that form a

robust, passive bus for up to 64 I/O interfaces. Each interface

has a matching I/O terminal block and can be installed in any

I/O slot on the bus. Carriers and interfaces can be added online,

without interruption to the existing I/O communication.

This modular design enables you to purchase the exact

amount of I/O cards, eight-wide carriers, power/controllers,

and two-wide carriers you need and add more DeltaV I/O

as your system grows.

Reduced installation time and expense: The DeltaV system’s

S-series I/O interfaces are designed for quick assembly and

error proof maintenance. All carriers snap onto T-DIN rails and

interfaces snap into the I/O slots without the use of any tools.

Each I/O interface has a separate wiring terminal block,

which connects field wiring to the interface. The I/O card can

easily be removed without touching the I/O wiring on the

terminal block. Some I/O cards can also use the fused terminal

block, which is equipped with in-line fuses that can be pulled

to isolate power to the field circuit.

Traditional I/O interfaces have I/O function keys that allow

the terminal block to be set to receive a specific I/O card.

These keys ensure that the correct I/O card is always plugged

into the corresponding terminal block. The keys provide a

safety measure by preventing the wrong I/O card being

installed. It’s incredibly easy to use and gives you time to

do more.

The I/O carriers provide integrated bussed field power

distribution to the I/O interfaces. The integrated bus is divided

into primary and secondary power for odd- and even-numbered

slots. Each slot is individually fused to protect power to other

cards. This significantly reduces the external power distribution

circuits while still providing each card with fused 24V DC bussed

field power.

Easy online expansion: The S-series I/O carriers and interfaces

can easily be added online, without disruption of existing

I/O communication. I/O carriers can be extended online,

either by directly connecting them to the right side of the

existing carrier, or using extender cables to mount the new

carrier on a different DIN rail. The controller automatically

detects new carriers and interfaces and allows these to be

auto-sensed into the configuration database.

Field-mounted capable hardware: All S-series traditional I/O

interfaces are rated for extreme operating temperature ranges

of -40 to 70°C (-40 to 158°F). The interfaces can be installed

in field mounted enclosures so you significantly reduce the

footprint of your equipment and increase valuable control room

space for other uses. This also allows you to save on wiring

expenses 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.

1:1 Redundancy for traditional I/O cards: Increased

system availability is easy with S-series traditional I/O cards.

Four traditional I/O card types are available with redundant

terminal blocks for critical field circuits. Simply install a pair
