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. www.honeywell-diver.com 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.
