EMERSON DeltaV™ M-series Traditional I/O

 Introduction
 Traditional I/O is a modular subsystem that offers flexibility 
during installation. It’s designed to be installed in the field, 
near your devices. Traditional 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™ Traditional I/O a smart choice for your process 
control system

Benefits
 Decreases capital equipment costs
 Full system modularity: The Traditional I/O subsystem was 
designed with your investment in mind. All components are 
fully modular and may be installable under power. You add  
I/O interface carriers and I/O interfaces in groups of 4, 8, 16,  
or 32 channels as you need them. The modular design enables 
you to purchase the exact amount of I/O cards, 8-wide or 
4-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.
 Installation: Save on wiring expenses by installing Classic 
Instrumentation 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 Traditional I/O 
subsystem can eliminate the need for marshalling 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.
 Decreases installation time and expense
 Plug-and-play installation saves money: All Traditional  
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.
 Keys: Traditional 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.
 This design enables you to initially install Traditional 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.

 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.
 Increases process availability
 1:1 Redundancy for Traditional and HART I/O cards: 
DeltaV redundant I/O uses the same Series 2 I/O cards as  
non- redundant I/O. This allows you to leverage your investment 
in installed I/O and in I/O spares. No additional configuration 
is needed when using a redundant channel. The redundant 
terminal blocks provide the same field wiring connections  
as simplex blocks, so there is no extra wiring needed.
 Autosense of redundancy: DeltaV autosenses redundant I/O, 
which greatly simplifies the task of adding redundancy to the 
system. The redundant pair of cards is treated as one card  
in the system tools.
 Automatic Switchover: Should a primary I/O card fail,  
the system automatically switches to the “standby” card 
without user intervention. The operator is given clear 
notification of a switchover at the operator display
