The WirelessHART I/O card provides redundant communication for up to 100 WirelessHART devices,

providing high availability and reliability of wireless data.

Up to 16 Wireless HART I/O cards can communicate to a single controller.

Control modules are automatically scheduled by the controller, based on their assigned scan rates.

This allows each control function to be optimized based on the process dynamics.

Modules scan times can be set as fast as 100 ms, and as slow as 60 seconds.

The number of control modules that can be assigned to a controller depends

on the complexity and scan rate of each module, and the available CPU and memory.

The SD Plus controller should be used for small to medium applications with a maximum of 750 individual I/O signals.

The SD Plus controller is designed for harsh environments and is rated for G3 corrosive environments,

with an operating temperature range from -40 to 70 ºC.

It is ideally suited for remote installation, close to the process equipment.

For more traditional installations with central marshalling cabinets,

CHARMS I/O cards can be mounted in standard I/O cabinets providing Electronic Marshalling.

CHARMS I/O Cards can also be used for highly distributed I/O applications.
