Emerson DeltaV™ SQ Controller Scalable Controller

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.

The CHARM I/O card (CIOC) connects through the controller's redundant Ethernet ports to provide a highly distributed and flexible I/O solution called an e-solution.

solution. Up to 16 CIOCs can be connected to a single controller, each providing up to 96 individually controllable signal types.

SQ controller capacity limits may vary depending on the specific application, number of CHARM I/O signals, and control performance requirements.

Enhanced Memory Handling and Hardware Alarms, Indexed to Cover Capacity and Memory

Enhanced memory handling and hardware alarms covering capacity and memory have been added to the SQ controller's diagnostic information through indexing.

The WirelessHART I/O Card (WIOC) provides redundant communications for up to 100 WirelessHART devices, ensuring high availability and reliability of wireless data.

Up to 16 WirelessHART I/O cards can be connected to a single controller, each providing up to 100 signals.

The controller automatically schedules control modules based on the assigned scan rate. This allows each control function to be dynamically optimized for the process.

Module scan times can be set as fast as 100 milliseconds and as slow as 60 seconds.

The number of control modules that can be assigned to the controller depends on the complexity and scan rate of each module, as well as the available CPU and memory.

The SQ controller is suitable for small to medium sized applications with up to 750 independent I/O signals.

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.
