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.
