Introduction
DeltaV™ M-series Intrinsically Safe Input/Output (I.S. I/O)
provides the perfect solution to the precarious situation of
running I/O in hazardous areas. DeltaV I.S. I/O is a distributed
I/O system capable of withstanding Class I Division 2 and Zone II
environmental conditions. The I.S. I/O subsystem connects field
circuits and field devices to the DeltaV system. Intrinsically safef
ield circuits and field devices can enter Class I Division 1.
Zone 1. and Zone 0. The DeltaV I.S. I/O supports industry
standard AI, AO, DI, and DO, applications.
Benefits
Features full system modularity. The I.S. I/O subsystem
was designed to optimize your automation investment.
All components are fully modular and installable under power.
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 buy the exact amount of I/O cards and power/controllers
that you need. Add more DeltaV I/O as your system grows.
Reduces system footprint. The state-of-the-art form
factor design of the DeltaV I/O components enables you to
mount the I/O interface carrier in a junction box in the field.
You significantly reduce the footprint of your equipment
and free up valuable control room space for other uses.
Decreases installation time and expense. DeltaV Intrinsically
Safe I/O are native DeltaV I/O cards that are part of the
controller’s I/O subsystem. This eliminates the need for third
party barriers or interface mapping. Save even further on wiring
expenses by installing I.S. I/O in the field, close to the actual

ield devices. Mounting the controller with the I/O further
reduces your wiring expenditures by eliminating the need
for long runs of multi-cores.
Plug-and-play installation saves money. The I.S. I/O
subsystem is easy to use. All I.S. I/O components plug into
the I/O interface carrier. You can install the I/O interface
carriers to manage anticipated growth, without purchasing
the I/O interfaces until you’re ready to install your additional
ield devices.
Phased installation saves time. Mount the I/O interface
carrier and you are ready to begin installing the field devices.
I/O terminal blocks plug directly onto the I/O interface carrier—
there’s no need to have the I/O cards installed.
Easy to use. I.S. 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—easy!
This fail-safe design enables you to initially install I.S.
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. DeltaV I.S. I/O—easy to install and maintain.
Real-time, online equipment additions. Online addition
of new I/O interfaces means your process does not get
interrupted. As new equipment is added, DeltaV Explorer
acknowledges it and assigns it basic configuration.
Product Description
A variety of analog and discrete I/O cards are 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 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.
(It is important to note that, when connecting standard I/O
carriers to I.S.I/O carriers, more standard I.O. carriers may
not be added after I.S. carriers—the I.S.I/O carriers must
always be mounted last in line.)
Intrinsically Safe Power Supply
The intrinsically safe power supply accepts 24 VDC power and converts it to 12 VDC to power the DeltaV I.S. I/O cards. The number
of I/O cards that can be powered by a single Intrinsically Safe Power Supply depends on the I. S. I/O card type. Optional power supply
redundancy is supported by adding power supplies at a rate of n + 1. The following table gives the specifications for the DeltaV I.S.
