Product Description

The SD Plus controller executes control logic based on the process signals derived

from the I/O subsystem and provides communication to the rest of

the DeltaV control system for operator interaction and data collection.

Each controller node can be installed as a simplex or redundant node.

Redundancy is provided by adding a second controller and power supply

mounted adjacent to the primary controller.

The controllers are connected to the I/O carriers, which are mounted to the right of the controller carriers.

Up to 8 carriers with 8 cards each can be connected to the local bus I/O, for a total of 64 traditional I/O cards.

In addition to the 8 local I/O carriers, each controller can communicate

with an additional 16 Remote I/O units hosting traditional card based I/O.

In addition to traditional I/O cards, the local bus supports field bus technologies,

including Foundation fieldbus, Profibus DP, DeviceNet and AS-I protocols.

The I/O subsystem also supports Serial interface cards as well as the Ethernet I/O interface.

These various I/O products provide a wide range of interfaces to meet the needs of your control application.

The SD Plus also supports CHARMS and WirelessHART IO cards.

The CHARMS I/O card (CIOC) connects via the redundant Ethernet

ports of the controller and provide a highly distributed and flexible I/O solution called Electronic Marshalling.
