Product description

For critical process control applications that cannot tolerate interruptions, the DeltaV system provides

controller redundancy.

For critical process control applications that cannot tolerate interruptions, DeltaV systems offer controller

redundancy.

The redundant controller contains the same control strategy as the active controller.

A redundant link transmits control parameters to the standby controller

to ensure that it is ready to take over from the active controller.

parameters to the standby controller to ensure that it is ready to take over control if needed.

When redundancy is enabled, each module calculates the updates required by the standby controller.

These updates are transmitted to the standby controller via the redundant link.

Designed for harsh environments, the SQ controller is rated for G3 corrosive

environments and has an operating temperature range of -40 to 70°C.

It is ideal for use close to process equipment.

It is ideal for remote installations close to process equipment.

For traditional installations using a central dispatch cabinet,

the CHARM I/O card can be installed in a standard I/O cabinet that provides electronic dispatch

capabilities.

The CHARM I/O card can also be used in highly distributed I/O applications.
