Product Description

The SQ controller executes control logic based on process signals from the I/O subsystem.

The SQ Controller executes control logic based on process signals from the I/O subsystem

and provides communication with 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.

Each controller node can be installed as a stand-alone or redundant node.

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

The controller is connected to an I/O carrier mounted on the right side of the controller carrier.

Up to 8 carriers can be connected to the local bus I/O.

Each carrier has 8 I/O cards for a total of 64 legacy I/O cards.

In addition to the 8 local input/output carriers, each controller can be connected to an additional 16 I/O carriers.

Each controller can also communicate with an additional 16 remote I/O units that carry legacy card-based inputs/outputs.

In addition to traditional I/O cards, the local bus supports Feldbus technologies including Foundation Feldbus, Proffbus DP, DeviceNet and AS-i protocols.

The I/O subsystem also supports serial interface cards and Ethernet I/O interfaces.

The SQ controller also supports CHARM and WirelessHART I/O cards.
