I/O carriers boost density but cut heat

An Emerson Process Management product story
Edited by the Engineeringtalk editorial team Jul 11, 2008

Vertical I/O is easier to install and maintain because cables coming from the bottom of cabinets can be fanned out and terminated without multiple wire bends.

Emerson Process Management has released the DeltaV VerticalPlus I/O carriers which extend the benefits of DeltaV vertical I/O to DeltaV SIS, providing flexible installation, increased I/O density and better thermal management for both DeltaV and DeltaV SIS applications.

The vertical carrier orientation reduces lifecycle costs through lower installation, maintenance and energy costs.

Vertical I/O is easier to install and maintain because cables coming from the bottom of cabinets can be fanned out and terminated without multiple wire bends.

This is consistent with current practices of delivering cables through the bottom of cabinets, especially in locations that have raised floors.

The overall air-conditioned cabinet footprint is reduced with vertical I/O and it provides better thermal management and improved airflow in cabinets due to the vertical orientation of cards.

The redesigned vertical carrier supports simplex and redundant DeltaV SIS modules that communicate via a redundant safety bus, which is separate from the basic process control system (BPCS) communications.

VerticalPlus carriers can also communicate secure SIS data via redundant SISNet Repeaters to other DeltaV SIS nodes on vertical and horizontal carriers.

A T-type DIN rail is all that is required to mount the power/controller carrier.

Bussed field power is now separate for each individual card.

The DeltaV system's modular design approach allows users to add I/O carriers as required.

DeltaV digital automation systems are a core component of Emerson's open, standards-based PlantWeb digital plant architecture, which substantially reduces project costs, with customers typically saving over 30% on installed costs.

The Emerson SIS solution enables customers to implement safer facilities, improve availability, lower life-cycle costs and ease regulatory compliance.
