The RIU2 supports 10/100MB communication on both primary

and secondary ports.

Data Passthrough. The controller is equipped with the

ability to pass smart HART® information from field devices

connected to a Remote I/O Unit to any workstation node

in the control network.

This means you can take advantage of applications, such as

AMS Device Manager that enable you to remotely manage the

HART information contained in your HART equipped devices.

Mounting. This plug-and-play system structure provides

modular system growth with a single controller and

is approved for remote mounting in a Class 1. Div 2 or

ATEX Zone 2 environment. Refer to the System Power

Supplies and I/O Subsystem Carriers product data sheets

for additional information.

I/O Types and Capacity. The RIU2 support one I/O carrier

of either Classic I/O or HART I/O. The Remote I/O Unit and

I/O cards can be installed on either horizontal or VerticalPlus

carriers. Any of the Classic or HART I/O cards may be utilized.

The HART data from the I/O channels can be used in a control

strategy, providing the user with the same experience using

remote I/O as when using local I/O.
