Emerson A6824 ModBus And Rack Interface, 6TE

Emerson has developed a DIN-rail mounted power supply incorporating four modular fanless powering systems

to provide reliable and stable power to the Ovation™ controller and I/O modules.

The Ovation controller powering system uses redundant configurations, each with separate, external wide-range AC and/or DC input feeds. 

Dual diode auctioneered 24 VDC outputs are used to power each controller chassis and associated I/O modules, as well as loops and contact wetting to the I/O modules. 

If required a 48 VDC auxiliary power for loops and contact wetting can also be provided. 

Two separate output schemes are available: 

▪ 24 VDC / 10 A / 240 W main and 24 VDC / 10 A / 240 W auxiliary power 

▪ 24 VDC / 20 A / 480 W main and 24 VDC / 20 A / 480 W auxiliary power

Benefits of the Ovation power supply scheme include: 

▪ Separate main and auxiliary power supplies allow easy replacement 

▪ Elimination of cooling fans greatly reduces failure risks 

▪ Diode auctioneered power feeds assure continuous power availability 

▪ New design increases efficiency, reduces heat generation and enhances equipment life expectancy 

▪ Dual input (AC and DC) capability reduces spare parts 

▪ Hot-swappable power supplies enable on-line replacement

▪ Quick installation of the power supplies minimizes downtime and production loss ▪ Power factor correction reduces power consumption

Embedding DeltaV InSight into the automation system improves both ease of use and calculation performance.

InSight is easy to use because there is no additional configuration required. InSight configuration is automatic:

every time a control loop is added, deleted, or modified in the control system,

InSight configuration is automatically updated with the latest configuration.
