The WirelessHART I/O card (WIOC) provides redundant

communication for up to 100 WirelessHART devices,

providing high availability and reliability of wireless data.

Up to 16 WirelessHART I/O cards can communicate to

one controller, each providing up to 100 signals.

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 SX controller should be used for medium to large

applications with a maximum of 1500 individual I/O signals.

The SX controller is designed for harsh environments and

is rated for G3 corrosive environments, with an operating

temperature range from -40 to 60°C.
